Post-doctoral vacancies in photonics

  • Post-doctoral position in Photonics: Multi-color lasers implemented on generic Photonic ICs

    Lasers with the capability to emit simultaneously at multiple wavelength, i.e. multi-color lasers, open exciting perspectives for a wide range of applications, from optical sensing to data-communication or mm-wave and THz all-optical processing. Combined with the outstanding and continuous progress of generic foundry platforms making Photonic Integrated Circuits widely available, it is now possible to design multi-color lasers specifically tailored for various applications. The main bottleneck of this development is the difficulty to finely control multi-color lasers. In short, depending on the internal mechanism, these lasers can either be versatile but extremely sensitive, or robust but without any practical control parameter. Yet, we recently proposed a new technique based on phase-controlled optical feedback which showed great promises. We were able to induce complete wavelength switch in two-colour laser with a suppression ratio up to 50 dB. Moreover, the feedback cavity can be monolithically integrated on the same chip than the laser, hence ensuring a low footprint of the complete system.

    Now, 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 optical signals all-optically. In this context, we are looking for an excellent PhD candidate in photonics (duration = 48 months) to join our team.

  • Post-Doctoral Position in Photonics. Laser dynamics induced by distributed optical feedback.

    The complexity of the dynamical behaviour of lasers, and especially semiconductor lasers, have been intensively investigated in the past 40 years. Some of these efforts were made in order to suppress unwanted dynamics while others tried to exploit it e.g. for secure communication or random number generation. The impact of feedback on laser dynamics is arguably one of the most studied cases, but in the last years, the use of distributed reflectors such as Bragg Gratings appeared as a new twist which is expected to open a lot of new opportunities and applications. Experimentally, the change is relatively small as we only need to exchange the commonly used mirror to a distributed reflector. However, the time distribution has a major impact on the theoretical modelling and renders some of the mathematical tools that have been used so far useless.

    Being currently working on two distinct projects linked with distributed feedback – to trigger broad bandwidth optical chaos on-chip on one hand, for accurate optical sensing on the other hand -, we are now looking for an excellent Post-Doctoral researcher in photonics to join our team to bridge these two ongoing projects through further investigation of the effect and underlying mechanism of distributed optical feedback. The research work will therefore include:

    - Theoretical investigation of the impact of distributed optical feedback on semiconductor laser
    - Processing and analysis of experimental measurements made in the frame of the two ongoing projects
    - Setting up, in collaboration with the team, specific experimental setups or measurements to gain further insight.
    - Design of new photonic integrated circuit schemes, again in collaboration with the team, to perform dedicated measurements or investigations.

    Beyond the scientific tasks, the post-doctoral researcher will be expected to take the following responsibilities:

    - Co-supervision of and collaboration with the two PhD students involved in the related projects.
    - Direct involvement as expert/advisor in the two ongoing projects
    - Active contribution to the writing of personal or collaborative project proposals. The post-doctoral researcher will indeed be given the opportunity to develop his own research activities and collaboration network.

    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.
