    Funded PhD Project (Students Worldwide)

Department of Electrical Engineering - Electro-Optical Communication, Eindhoven University of Technology

Project Description

In the Electro-Optical Communication Systems (ECO) group, department of Electrical Engineering. The PhD position relates to the European H2020 project PASSION where Eindhoven University of Technology collaborates with leading industrial and academic partners as well as a number of small and medium enterprises on future solutions for Petabit/sec transmission systems. In order to support the future growth in demand for bandwidth cost effective and modular optical transmission modules have to be developed. The effort of Eindhoven University of Technology within the PASSION project relates to the hardware developments and in particular Transceiver design. This position relates to the integration of vertical coupled surface emitting lasers (VCSELs) with other photonic integration platforms to achieve record bandwidth density solutions with substantial reduction in cost and power consumption. Based on novel TU/e approach for die integration we will collaborate with other academic and industrial partners to deliver novel solutions.
Within the PASSION project the PhD student is required to further develop our assembly process. In particular we wish to address the following topics:
1. Scaling the stacking technology to devices that operate at higher bit-rate and have larger size (e.g 16 Tbps)
2. Supporting co integration of VCSELs with adjacent planar optical integration technologies.
3. Introducing new schemes of integration for improved signal integrity
4. Development of machine manufacturable packaging technologies for three and 2.5 dimensional devices.

The work will include both process-development in a cleanroom environment as well as practical development of packaging solutions in an industrial context. We wish to get in contact with candidates that have strong technical background. Since strong interaction with our industrial partners is required strong communication skills are also essential. Candidates for the PhD position should have a Master’s degree in Electrical Engineering, with excellent grades.

Tunable infrared photodetectors based on 2D materials

Tunable infrared photodetectors based on 2D materials

 Engineering Physics, Ecole Polytechnique de Montreal

Project Description

Context:
The Laboratory for Nanostructured and Molecular Photonics (http://www.polymtl.ca/lnmp/en) is seeking outstanding students to work on the development of infrared photodetectors based on nanostructured black phosphorus. Black phosphorus is a stable allotrope of phosphorus with a layered structure that can be exfoliated, like graphene, down to a single monolayer. It possesses several distinctive features: remarkably high carrier mobilities, an anisotropic band structure, and a direct bandgap to efficiently absorb light. Most importantly, it shows two characteristics unmatched by any other 2D or bulk materials: a tunable direct bandgap from the mid-infrared to the visible via the sample thickness and the ability to dynamically tune the gap through an applied electric field.

Project:
In partnership with Excelitas Technologies, a global leader in optoelectronic components, the Laboratory for Nanostructured and Molecular Photonics is seeking graduate student applications for the development of efficient and tunable photodectors based on exfoliated layers of ultrathin black phosphorus and black phosphorus quantum dots. This project will involve photodetector design, exfoliation and/or synthesis of nanostructured black phosphorus, device fabrication and characterization.

Relevant skills:
Students with backgrounds in Physics, Electrical Engineering and Materials Science/Chemistry are invited to apply. Skills relevant to these projects include an excellent understanding of semiconductor device physics, 2D materials, optical spectroscopy, inorganic synthesis, and micro/nano-fabrication. Previous experience in any of these areas will be considered assets for the project.

Funding:
PhD studentships will be fully-funded for the duration of the project. Outstanding students will be encouraged for prestigious provincial (FRQNT PBEEE) and national fellowships (NSERC Vanier).

About the group:
The Laboratory for Nanostructued and Molecular Photonics is led by Prof. Stéphane Kéna-Cohen, the Canada Research Chair in Hybrid and Molecular Photonics. It is currently composed of 6 graduate students and 1 post-doctoral researcher. The group is active in the development of optoelectronic devices based on novel materials as well as quantum optics.

Development of Soft Sensors for the manufacturing of drug-eluting implants

Development of Soft Sensors for the manufacturing of drug-eluting implants

  • Applications accepted all year round
  • Funded PhD Project (Students Worldwide)

Precision Engineering, Materials and Manufacturing (PEM) Research Centre, Institute of Technology, Sligo

Project Description

Medical implants are increasingly seeing the incorporation of Active Pharmaceutical Ingredients (API) to reduce implant site complications and improve biocompatibility. Such molecules include antibacterial drugs, immunosuppressive drugs, anti-inflammatory drugs, or APIs that in various ways stimulate cellular proliferation and tissue regeneration. Implant materials suited for drug release purposes are typically bioresorbable polymers such as polylactic acid (PLA) which degrade over time into non-toxic byproducts while slowly but continuously releasing the drug trapped within its matrix. Ideally the polymer provides initial mechanical support (e.g. cardiovascular stent, bone fixation screw etc.) and degrades completely over time as the host tissue heal and the implant is no longer required.
The incorporation of drug into polymer can be done in a number of different ways but Hot Melt Extrusion (HME) has a number of advantages over other methods including: enhanced bioavailability of poorly soluble drugs; fewer processing steps; less scale-up issues resulting in a shorter development time; possible automation of the production line; reduction of production costs and waste; a reduced time to market; less product variability and improved product quality.
However HME of such devices is still complex and expensive with long development times — not only in the formulation of the product but also in identifying suitable process conditions and adapting to variations between batches of raw materials. Processing conditions affect the degradation of the polymer, degradation of the drug, drug-polymer interaction, dispersion of the API, the crystallinity of the drug and other factors critical to mechanical properties and drug release behaviour. The effect of process settings on these factors are not well understood and the industry is still dominated by off-line quality testing in a laboratory with very slow feedback to adjusting the process parameters.
The proposed research targets this knowledge gap by aiming to use on-line process measurements, including Process Analytical Technology (PAT) to predict key final product quality characteristics in real-time during processing using mathematical modelling techniques. The successful candidate will research a variety of process sensors; set-up a data acquisition system; run plant trials; carry out a variety of product characterisation tests in the lab and explore modelling techniques capable of predicting the product quality from the available in-process data. Multivariate analysis and machine learning techniques will be explored as appropriate.
Research questions to be addressed:
1. How do extrusion processing parameters affect the quality of extruded bioresorbable API-loaded medical implants?
2. Can in-process Raman and/or NIR spectroscopy data yield real-time insight to the structure and properties of the drug-polymer systems for the production of such implants?
3. Is it possible to use this data, with or without other process data, to predict final product quality metrics in real-time with similar accuracy to conventional off-line laboratory testing?
The outcomes of the research have the potential to reduce development time and costs of new innovative medical devices with ultimate benefits to patients.

MRes Characterisation of the dynamic fatigue performance of optical fibres with Nickel based coatings

MRes Characterisation of the dynamic fatigue performance of optical fibres with Nickel based coatings

Applications accepted all year round
Competition Funded PhD Project (Students Worldwide)

Research Centre, Institute of Technology, Carlow

Project Description

Project Objectives

The overarching aim of this proposed research work is: To characterise the dynamic behaviour of FBG inscribed optical fibres with Nickle based coatings. The key objectives of the research programme are to:
— Design and build a two-point bend tester suitable to determine the strength and dynamic fatigue parameters of the coated fibres.
— Specify and manufacture six coated fibres confirm dimensions of manufactured samples prior to testing.
— Carry out a series of dynamic fatigue tests using the newly developed tester to determine the failure stress or failure strain under different loading rates.

Methodology proposed

The two point bend test is a standard method of investigating the mechanical properties of coated and uncoated optical fibre as it eliminates gripping problems experienced by other methods. A tester will be developed that can achieve constant strain rate, constant stress rate and constant velocity to achieve results comparable to those obtained from a standard tensile test. From literature the faceplate velocities of the tester need to be in the range 50 – 4000 µms-1. The dynamic fatigue test will be conducted on six coated fibres and one uncoated fibre to ascertain the failure stress of each.

Expected outcomes: (e.g. deliverables & strategic impacts)

The proposed research is allied with one of engCOREs three thematic areas of research, namely, Smart Materials and Mechanics. This thematic area in turn is aligned with one of the research priorities (Manufacturing & Materials) identified in Innovation 2020, Ireland’s strategy for Research and Development, Science and Technology.

The proposed research will be investigate for the first time the effect of Nickle based coatings on the fatigue behaviour of optical fibre. Nickle based coatings are now being used in the Additive Manufacturing sector to protect silica fibres during high temperature embedment with Titanium and Stainless components.

Results obtained from this research will be disseminated through high impact factor peer reviewed journals (Indexed in Web of Science/Scopus), such as Smart Materials & Structures and Materials Science and Engineering.

Hardware Security for Contactless 3-D Integrated Circuits

Hardware Security for Contactless 3-D Integrated Circuits

  • Applications accepted all year round
  • Competition Funded PhD Project (Students Worldwide)

Project Description

Hardware security has become a pressing issue for a broad variety of integrated systems developed for applications that process and/or store sensitive personal data. Although there are plenty of security methods to cipher this data, there has also been shown that several types of attacks can breach security thereby accessing the crucial data. A specific type of these threats, known more broadly as side-channel attacks [1], is called power analysis attacks [2] where the information about the encryption algorithm of the circuit and the key can be obtained by observing the power profile of the circuit (typically by non-invasively accessing some of its power pins).

The research question that this project intends to address is how these threats manifest for three-dimensional (3-D) circuits [3] and how they can be mitigated. In principle, the stacking of circuits is considered to increase the security strength of the system; however, this may not be the case for contactless 3-D circuits where power is also transferred wirelessly through on-chip inductors.

The student will investigate whether similar security attacks as those to RF tags can be applied to this type of circuits and propose countermeasures for this type of attacks. Obfuscation methods, modulation of the transferred power to mask the power profile of the executed by the circuit task are some possible ways to address these security issues. The focus will be on sensing based systems which process, extract, and potentially store sensitive medical information.

This PhD project offers an exciting opportunity to work primarily in developing new ideas that will lead to novel design methods for securing this type of 3-D circuits. The student will have the opportunity to design test circuits through multi-project wafer services and thus evaluate the efficiency of the proposed methods through silicon measurements. Consequently, high quality and impactful publications are expected to be produced during the course of this project. Circuit design skills, knowledge of 3-D integration and heterogeneous technologies as well as deep understanding of hardware security will be acquired, all of which are key elements for careers in the semiconductor and more broadly the electronics industry.

Keywords: Hardware security, side-channel attacks, three-dimensional integration, cryptography.

Project Description

Electrification of aircraft leads to reduced carbon emission and reduced noises, which has become a new research focus of aviation industry. Large electric aircraft requires high power density propulsion machines, which cannot be met by conventional solutions. High temperature superconductors can carry large amount of current with little losses, so they are ideal to construct machines with high power density. The PhD project will be focusing on developing propulsion machines with particular high power densities for electric aircraft, by using the latest high temperature superconductors. The application is expected to design, model and develop components of the superconducting machines, in order to understand the overall machine performance. The project also involves using new machine configurations to optimise power density. Superconducting propulsion machines connected with superconducting network will be studied numerically. In particular, the response of the machine under fault scenarios need to be studied to develop proper protection schemes.
