| Abstract: | We achieved apodization in a quasi-phase-matched wavelength converter. The new design yields a large bandwidth and a flat phase-matching response with a high conversion efficiency. Using the method, we demonstrate widely tunable 3.4 microm band difference frequency generation in a LiNbO3 ridge waveguide. |
