Broadband second harmonic generation by birefringent phase matching in an X-cut LiNbO3 membrane
Abstract
We designed an X-cut lithium niobate (LiNbO3) membrane dedicated to type I second harmonic generation (SHG) at telecom wavelength. A competitive conversion efficiency compared to a quasi-phase-matched configuration with the advantage of a broadband response of 100nm is shown.
