description

The application of surface periodic poling method for first order quasi-phase-matched (QPM) second harmonic generation (SHG) in Ti:indiffused lithium niobate channel waveguides, was investigated. On a 2.5 μm wide channel waveguide which was periodically poled with a period of 2.47 μm for TM waveguide mode interaction, efficient SHG was observed. The CCD camera was used for monitoring the near-field waveguide mode profiles of both the fundamental and second harmonic waves. The potential of surface domain inversion for efficient nonlinear waveguide interactions was shown after the production of 6 mW of continous-wave blue radiation.
