Motivation and context
Photonics is regarded as a key enabling technology by the European Commission and its application and use in many scientific and industrial fields is accelerated through Photonic Integrated Circuits (PICs). The photonic integration research group (PhI) at TU/e has pioneered the concept of generic photonic integration platforms and continues to engage in research and development activities to extend the capabilities of such platforms based on the InP material system. It coordinates JePPIX, the Joint European Platform for Photonic Integration of Components and Circuits, and works together with Europe's main players in the photonic integration industry to provide access to this technology and enhance existing platforms.
Together with our partners, we aim to extend the InP platform capabilities with components for integrated coherent receivers and will initiate this activity in a soon to start European H2020 project which focuses on InP PICs for next-generation metro and access networks. We are looking for a postdoctoral researcher that is eager to take this opportunity and perform innovative research and development on integrated coherent receivers. The candidate is expected to work in close collaboration with project partners involving well-known knowledge institutes and companies within the PIC industry.
The candidate is expected to research and design integrated coherent receiver circuits on a generic InP integration platform. In particular, different methods for achieving widely tunable, low linewidth lasers and high-speed balanced photodetectors shall be devised and implemented. Their integration with optical hybrids into complete receiver circuits shall be investigated and performed on the generic platform. Challenges related to processing technology shall be identified and overcome.
