Study of Optical Losses in SiNx and SiOxNy Coatings Deposited by Plasma-enhanced Chemical Vapour Deposition for Gravitational Wave Detection

Year: 2025

Type: conference-paper

Abstract: Gravitational wave detectors rely on low mechanical and optical loss mirror coatings. This work discusses optical losses through absorption and light scattering mechanisms in SiNx and SiOxNy coatings deposited by plasma-enhanced chemical vapour deposition.
