Abstract :
The first example of second harmonic generation (SHG) in an ion implanted KTiOPO4 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.
