FP-49 PhD – High-speed photonics using quantum well intermixing for micro- transfer printing

Contract: Full Time/Fixed Term

The IPIC II / PIADS project is calling for a new position in high-speed photonics based at the Tyndall National Institution and University College Cork and in collaboration with the University of Glasgow. The PhD position is focussed on developing high-speed photonic integrated circuits designed for micro-transfer printing. In this project quantum well intermixing will be used to create materials with different optical properties in the same chip.

Key Responsibilities and research objectives

Photonic integrated circuits (PICs) is a rapidly growing area of research and development that has accelerated due to the adoption of silicon photonics. Silicon still suffers from the lack of any viable laser source and suffers from poor performance of optical modulators. III-V PICs can include both good lasers as well as very fast optical modulators, but do not have the manufacturing scale of silicon. Micro-transfer printing (μTP) provides an outstanding method of integrating III-V and silicon PICs, although integration challenges persist for high-speed devices. This project aims to solve many of these challenges in developing very high-speed III-V PICs that are compatible with silicon via μTP. Rather than merely generating single photonic devices (lasers or modulators), the goal of this project is to also demonstrate integrated III-V PICs using quantum well intermixing.

The successful candidate will work in the group of Prof. F. Peters and in collaboration with Dr. E Pelucchi (epitaxial growth), Dr. Lianping Hou from University of Glasgow (quantum well intermixing) and Dr B. Corbett (micro- transfer printing) to develop high-speed integrated PICs for hybrid integration. This effort is aligned with and will also collaborate with the IPIC/Tyndall program in heterogeneous integration. The PhD candidate is expected to collaborate intensively with the rest of the research groups on subjects close to the PhD topics, contributing to a vibrant undergraduate research community.
