Towards fully integrated on-chip spectroscopy: optical frequency combs and supercontinuum generation in SiN and III-V waveguides


Silicon photonics technology, traditionally developed for optical communications, has been expanding over years towards broader applications from sensing to Lidar, microwave and quantum photonics... While relying on the very mature CMOS fabrication processes, silicon photonics is now starting to benefit from the integration of non-standard and non-silicon materials such as III-V and ultralow-loss SiN.

 

In this context, the objective of the internship is to explore the nonlinear optical properties of SiN and III-V devices fabricated in the 200mm and 300mm platforms of imec, with an outlook towards the generation of supercontinuum and optical frequency combs. The observation of such phenomena will constitute the backbone of the realization of CMOS-compatible on-chip spectrometers and frequency synthesizers.

 

During the internship, the successful candidate will be working on nonlinear optical simulations and characterization of fabricated devices. 


Activities

- Literature review on on-chip optical frequency combs and supercontinuum generation

- Modelling of nonlinear optical processes and devices

- Optical characterization of fabricated devices
