Fabrication and Characterization of Low-Loss SiN Waveguides
Silicon nitride (SiN) has become a key material in integrated photonics and is increasingly seen as a potential replacement for silicon as the main waveguiding platform. Its advantages—low optical losses, a wide transparency range, high power handling, and easier coupling to fiber modes—make it ideal for a broad range of applications. These include telecommunications, data centers, biosensing, LiDAR, and emerging quantum technologies. In our lab, we focus on its application in heterogeneous integration with an active material for electro-optic modulation, enabling high-speed and efficient signal processing. Show details

Master Thesis
Description
As part of this thesis, you will fabricate and characterize SiN waveguides and ring resonators at the Binning and Rohrer Nanotechnology Center (BRNC). You will deposit SiN using chemical vapor deposition methods, pattern photonic waveguides with dry etching methods and analyze the sidewall angles and surface roughness using a scanning electron microscope (FIB-SEM). Finally, the devices will be tested in the lab to measure optical performance and properties.
Type of Work
Literature (10%), simulations (15%), fabrication (50%) and characterization & analysis (25%) of photonic integrated circuits (PICs).
Requirements
Interest in nanofabrication and process development. Cleanroom experience is advantageous.
