Abstract :
We achieved apodization in a quasi-phase-matched wavelength converter. The new design provides an increased bandwidth and a flat phase-matching response with high conversion efficiency. We demonstrate widely tunable 3.4-μm-band difference frequency generation in a LiNbO 3 waveguide device.
