Jump to: navigation, search


Over the years, we developed a unique technology to bring a material with extremely strong Pockels coefficients into a scalable silicon photonic platform. Having such physical effect available in integrated photonics circuits has been a scientific and technological breakthrough, which enables the realization of advanced photonic structures and completely new applications, e.g. for photonic AI networks and quantum computing. At Lumiphase, we are bringing this new technology to market, while at the same time developing new scientific and technological concepts. The internship project is placed in the heart of our R&D activities and covers topics related to optical design and simulations, having the designs fabricated, and perform photonic characterization on them.

Details about the project

During this master or internship project, you will work in tight interaction with the Lumiphase R&D team to develop a waveguide-based, passive photonic component in an advanced, integrated photonic platform. You will perform theoretical and practical work, giving you a broad background into industrial driven R&D activities in the field of integrated photonics for optical communication. The work during the internship is technology driven, and includes

  • Simulations of photonic structures using advanced simulation tools (e.g. COMSOL, Lumerical, …)
  • Generation of photonic mask designs
  • Performing optical measurements using fiber-optical characterization setups and photonic chips fabricated by the

Lumiphase team

  • Analyzing experimental data, including the development of scripts, data visualization, and error analysis.

The duration of the project work will be 6 months. Your main work location will be in the Zurich area.

Status: Available
