Gain material integration on silicon and silicon nitride for integrated photonics light source in a 200/300 mm CMOS pilot line

PhD - Leuven | More than two weeks ago

Be part of a roadmap towards scalable integration of lasers on silicon

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, although the integration of on-chip coherent light source has been standing long as a major roadblock for the massive deployment of PICs at low cost.

 

Imec has been working on the development of new methods to realize on-chip light sources that are compatible with advanced CMOS foundry processing. In this context, the objective of the PhD is to work on the integration of gain materials in the 200 mm and 300 mm platforms of imec, with an outlook towards realization of integrated lasers-on-Si/SiN. The PhD topic will be devoted to the realization of EO-devices relying on the integration of materials spanning from III-V semiconductors to rare earths, while the wavelength range will span from the visible to the mid-infrared.


What you will do

Over the course of your PhD, you will work on optical simulations and laser design, some part of the fabrication of electro-optical devices and their characterization. You will be part of a multidisciplinary team and will stand at the boundary between applied research and industry. You will learn the way of working in a CMOS fab, photonics design, many different characterization techniques, how to lead your own research project and present your results to the scientific community.


What imec will offer you

Working at imec as a PhD student will bring you:

  • An industrial R&D environment with perspective to impact industry and go beyond a proof-of-concept.
  • Going from design and manufacturing process development to demonstration/characterization
  • Access to state-of-the-art technology
  • A contact with applications such as life sciences / high end metrology

 

Who you are

  • You hold a MSc degree in the following fields: Applied Physics, Electrical Engineering, Optical Engineering
  • You have a strong interest in photonics and a strong background in semiconductor physics
  • You have a good knowledge of Python/MATLAB.
  • Hands-on experience on an optical setup and basic knowledge of semiconductor processing in a CMOS line would be a plus.
  • Autonomy, scientific curiosity, and ability to work in an international environment
  • A strong commitment towards your work is expected


Required background: MSc degree in the following fields: Applied Physics, Electrical Engineering, Optical Engineering

Type of work: Literature study (10%), simulation (30%), processing (30%), characterization (30%)
