Development of wavelength converter based on quasi-phase-matched PPMgLN waveguide

摘要

We demonstrated C-L band wavelength conversion based on Quasi-Phase-Matched (QPM) PPMgLN waveguide. Cascaded nonlinear wavelength conversion was confirmed by using the PPMgLN waveguide with Grating period of 17.4μm, length of 30mm at room temperature. Conversion efficiency of -7dB was obtained for C-L band conversion at the pump power of 43dBm (24W) pulse.
