We propose a novel approach for efficient frequency doubling of near infrared light, using the coupled system of buried and surface waveguides obtainable by Reverse Proton Exchange in z-cut lithium niobate. In such guides, supporting TM and TE polarizations, respectively, in spite of the use of the d31 nonlinear element, we predict conversion efficiencies as high as 90 % or 14 % μm/W cm in planar structures excited at 1.32 μm.

Abstract
We propose a novel approach for efficient frequency doubling of near infrared light, using the coupled system of buried and surface waveguides obtainable by Reverse Proton Exchange in z-cut lithium niobate. In such guides, supporting TM and TE polarizations, respectively, in spite of the use of the d31 nonlinear element, we predict conversion efficiencies as high as 90 % or 14 % μm/W cm in planar structures excited at 1.32 μm.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
