High efficiency second harmonic generation of blue light on thin film lithium niobate

Abstract

We demonstrate second harmonic generation of blue light on an integrated thin-film lithium niobate waveguide and observe a conversion efficiency of ${\eta }_0=33000\%/{\text{W-cm}}^2$, significantly exceeding previous demonstrations.
