Job description

Silicon photonics is a field that is maturing and attracting strong interest from industry and academia to realize miniaturized photonic systems for applications in datacommunication, telecommunication and sensing, as well as in other emerging fields. While silicon-on-insulator is a mature platform for 1.3-1.55um platform, there is a need for alternative waveguide platforms to address applications outside the telecommunication window. For mid-IR wavelengths (>4um) the Ge-on-Si platform stands out as very valuable platform, due to its CMOS compatibility and wide transparency window. In the past years the Photonics Research Group has been developing such a platform for the 5-8um wavelength range, obtaining low loss waveguides, passive optical functions and thermo-optic tuning. However, currently the platform lacks the possibility to integrate III-V quantum cascade lasers (through flip-chip integration) and systems should be built based on this platform that address real-life sensing applications. You will be working together with industrial and academic partners in the H2020 project HYDROPTICS. The project aims at making use of novel advances in photonics, to provide a set of tools and devices, which allow the reliable and cost-effective monitoring of water quality involved in up- and downstream processing in the oil industry. HYDROPTICS will make use of novel mid-IR light sources, with a focus on quantum cascade frequency combs, in order to do dual comb spectroscopy on water samples to detect the presence of oil contaminants in water. Your goal is to build a miniaturized dual-comb spectrometer, based on the Ge-on-Si waveguide platform and with flip-chip integrated quantum cascade comb sources. You will design, fabricate and test the required photonic integrated circuits, as well as develop the processes required to enable the flip-chip integration of the quantum cascade lasers (in cooperation with CMST – another imec research group at Ghent University). Towards the end of the project you will interact with the end-users of the sensing system, in order for them to be able to do sensing experiments in real-life situations.

Profile of the candidate

You have a PhD in integrated optics, preferably in Silicon Photonics. You have a strong track record in the design, fabrication and test of photonic integrated circuits. Experience with midIR photonic integrated circuits is a plus. You have a broad view on photonic sensing applications, the advantages that photonic integration can bring for these applications and well as the challenges that need to be overcome. You have a good understanding of packaging technologies, flip-chip integration in particular. You possess strong verbal and written English communication skills allowing you to effectively communicate with industrial and academic partners, also those that are not experts in photonics and photonic integrated circuits.
