Would you like to perform excellent research in the field of integrated photonics and contribute to the rapid advances in this field? Do you want to push photonic components beyond their state-of-the-art in terms of speed and energy efficiency and address the technological challenges for that? Then you should read on and consider applying to this Postdoctoral Researcher position.Background
Today's high-tech systems for Internet of Things (IoT), Information and Communication Technologies (ICT) and high-performance computing within datacenters are all based on various technologies, nodes, components with their underlying fabrication processes and material systems. Mixing and matching technologies that are best suited for the target application through heterogeneous integration becomes very attractive as such resulting systems can provide an extended set of functionalities at high performance, small form-factor and increased energy efficiency. Integrated Photonics
is one of the key enabling technologies for high-speed, low-loss information transport and processing and poised to play a big role in the more than Moore paradigm shift.
The Photonics Integration
(PHI) group performs leading edge research into indium phosphide semiconductor based technology for photonic integration and its applications. You will become part of the group, contributing to the heterogeneous and nanophotonic integration research lines and be involved in a number of national and international research projects.

This position is part of the HiCONNECTS (Heterogeneous Integration for Connectivity and Sustainability) project within the EU Key Digital Technologies Joint Undertaking
framework. HiCONNECTS aims to support major societal and industrial challenges by developing heterogenous integration (HI) core technology solutions for energy-efficient and high-performance wireless/wired cloud and edge computing as well as automotive radar to solve two of the main state-of-the-art roadblocks: the transmission of Internet of Things (IoT) data over the IT network and sensing of objects to enable Highly Automated Driving (HAD). The role of TU/e in the project is to research novel data processing in edge computing, improve integration technology and perform testing of heterogeneously integrated electronic and photonic components.
You will be working together with other researchers in the EE department (ECO and IC group) to develop and realize highly efficient, ultra-fast optical transmitters on an InP membrane platform that are suitable to be heterogeneously integrated with driving electronics.
You will get familiar with the existing integration platforms and processes, advance and extend those to enable a new class of 100 GHz components. Within the project, you will be challenged on both design and technology. On the design side, you will take our existing know-how forward and propose a modulator design on InP membrane capable to reach 100 GHz bandwidth. On the technology side you will dive into the active-passive integration and membrane heterogenous integration technologies developed in the PHI group. Concrete challenges include:
- Optical and RF optimization of the modulator structure on an insulated membrane, with the aim of a low Vpi, high bandwidth modulator.
- Optimization of full active-passive integration process for high laser power and electro-optic modulation efficiency.
- Realizing broadband metallization processes with reduced parasitics and accurate dimension control.
- Gain insights into high-speed, fabrication-robust device designs.
Using the university's elite cleanroom
facilities, you will be able to realize novel concepts and components for proof-of-concept. You are expected to closely collaborate with other researchers and efforts in the group for high-speed, energy-efficient TRx components. Furthermore, within the HiConnect project, you will interact with a wide range of other EU partners in order to advance heterogeneous integration technology to the next level.Institute Embedding
The newly established Eindhoven Hendrik Casimir Institute
(EHCI) has the goal to bring together photonics, electronics and quantum technology and drives exponential computing, communication and sensing technologies, to enable a sustainable information society. You will be part of the EHCI focus area on High-bandwidth & energy-efficient optical interconnects
and your work will benefit from and bring synergy to other researchers within the institute.
