Abstract

We propose an X-cut LiNbO3 non-linear waveguide based on a thin film membrane. The structure allows second harmonic generation by birefringence phase matching between the two fundamental modes TE00 (SHG) and TM00 (Pump) at telecom wavelength. We demonstrate a competitive conversion efficiency compared to a quasi-phase-matched configuration with the advantage of a broadband response of 100nm and high manufacturing tolerance.
