摘要：
In this work, we demonstrate the use of hot-wire chemical vapour deposition (HWCVD) as an alternative technique to grow SiN layers for photonic waveguides at temperatures <400 degrees C. In particular, the effect of the ammonia flow and the filament temperature on the material structure, optical properties and propagation losses of the deposited films was investigated. SiN layers with good thickness uniformity, roughness as low as 0.61nm and H concentration as low as 10.4x10 21 atoms/cm(3) were obtained. Waveguides fabricated on the studied materials exhibited losses as low as 7.1 and 12.3 dB/cm at 1310 and 1550nm respectively.
