Quasi-phase-matched wavelength converter with adhered ridge waveguide for hybrid silicon photonics

摘要

A Mg:LiNbO{sub}3-based adhered ridge waveguide was fabricated by dry etching on a silicon platform. Efficient QPM-SHG (normalized efficiency: 450%/W) and -DFG (efficiency: -9.8 dB for pump power 38 mW) were achieved in the telecommunication band.
