Not Accessible

Your library or personal account may give you access

Abstract

We report a theoretical analysis of second-order nonlinear conversion by combining modal phase matching and bound state in the continuum in SiN strip loaded lithium niobate on insulator waveguides predicting an efficiency of 400% W-1 cm-2
