| Abstract: | The first example of second harmonic generation (SHG) in an ion implanted KTiOPO/sub 4/ waveguide is reported. This was formed by helium implantation, and SHG was achieved using zero order mode phase matching at lambda approximately=1.07 mu m. The results indicate that the high nonlinearity remains in the guiding region after implantation. The conversion efficiency in the guide is estimated to be >10% for approximately 1 mu J 20 ns pulsed excitation.<> |
