PhD Position in Photonics. multi-color lasers for mm-wave all-optical processing applications

In the frame of a Starting Grant from the European Research Council: ERC-StG-2020 project COLOR’UP (, we want to focus on the dynamics of multi-color lasers and investigate how they could be exploited for processing exploited for all-optical processing of mm-wave and THz signals. In this context, we are looking for an excellent PhD candidate in photonics (duration = 48 months) to join our team. The research work will therefore include:

  • Design and simulation of novel multi-color laser structures compatible with the constraints of the generic foundry platform
  • Testing, validation, and detailed characterization of the photonic ICs (PICs)
  • Development of new solutions to improve the current feedback-based control technique to achieve complete and precise control of multi-color lasers.
  • Investigations of the impact of feedback on the laser dynamics and mode competition.
  • Identification of processing capabilities and development of a demonstrator.



The candidate will join the Brussels Photonics (B-PHOT) research group of the Vrije Universiteit Brussel (VUB) in Belgium, Chaired by Prof. H. Thienpont, the team composed of more than 45 internationally recognized researchers is widely known for its work in fundamental and applied photonics research covering the entire research cycle from modelling and fabrication, to characterization and Proof-Of-Concept. In the last 20 years, the group has built significant expertise in the field of semiconductor laser – including modelling, design and on-chip implementation of new laser structures – but also in nonlinear dynamics and chaos-based applications. The candidate will therefore have the opportunity to contribute to the field in a vivid and fruitful environment.

Starting date: September – October 2021.

VUB is dedicated to promoting the role of women in science, and, therefore, explicitly invites women to apply.
