Conference paper
Theoretically, increasing the mode confinement is the way to go to improve the nonlinear efficiency, and we are actively working in this direction [1], but up to know there are still fabrications issues to solve to get low loss, highly confining waveguides with preserved nonlinearities in PPLN. Therefore, we are still intensively studying the...
