Job description

Eindhoven University of Technology (TU/e) has the following PhD student vacancy for research on high-speed optical transceivers for datacenters, in the research group Photonic Integration (PhI) of the department of Electrical Engineering.

PhD Position: Optoelectronic engines for next generation datacenter interconnection

Job description
Rapidly growing cloud applications, big data, Internet-of-Things (IoT), artificial intelligence (AI) and machine learning are the main drivers for the explosion of datacenter traffic which is foreseen to reach 19.5 ZB per year by 2021 ramping up from 6 ZB in 2016. The increasing traffic demands impose a huge challenge for datacenter operators since they have to keep pace with the increasing speeds dictated by modern datacenter applications. The transceiver modules need to evolve to higher operation speed and more parallel channels, in order to meet the speed demands.

Photonic integrated circuits (PICs) based on Indium Phosphide (InP) material system offers a powerful tool to the datacenter interconnection challenge. The InP-based PICs can integrate lasers, modulators, detectors and waveguide circuitry in a single chip with benefits of speed, efficiency, size and cost.

We have two PhD positions in a large EU-funded project TWILIGHT. In this project, TU/e has a central role in the development of optoelectronic engines for next-generation datacenter transceivers and switch matrices. The optoelectronic engines will be powered by the InP photonic membrane technology, which will be further co-designed and co-integrated with partner’s high performance InP-HBT electronics ICs to realize advanced system-in-package (SiP).

PhD position: High speed datacenter transceivers on an InP membrane nanophotonic platform
This position will develop high-speed transceivers on the InP membrane platform, in close cooperation with our partners in KTH, Sweden. The project will include device-level simulations (optical, electrical, thermal), device and circuit layout, process flow design, and device fabrication in the Nanolab@TUe cleanroom.

The team
The Institute for Photonic Integration (IPI) has five dynamic and ambitious research groups, which are closely cooperating: a systems group, a photonic integration technology group and three materials research groups. You will work in the Photonic Integration group (PhI) which has about 35 members, 20 of which are PhD students. The IPI (previously COBRA) is internationally leading on advanced InP-based Photonic Integrated Circuits technology. See The technology development and device realization will be supported by experienced technicians in our world-class cleanroom facilities at Nanolab@TU/e (

Job requirements
