Abstract
An angular coupling configuration is shown to facilitate phase-matched second harmonic generation between the TE1 fundamental and TE4 second harmonic modes of a LiNbO3 planar waveguide. For an incident coupling angle of 10°, 2.6% coupling efficiency is achieved for the TE1 waveguide mode, thus permitting visible light generation at the wavelength of 402.4 nm through phase-matching to the TE4 second harmonic mode. For a 2.8 mm-long LiNbO3 planar waveguide excited at an energy of 1.8 nJ, the second harmonic generation conversion efficiency is 4.6 × 10−5. The ability of this angular coupling scheme to facilitate phase-matched frequency-conversion makes it ideal for use in optical computing, optical communications, and quantum computing.
