| Abstract: | We present in this paper the fabrication and characterization of type Ⅱ waveguide in c-cut periodically poled KTiOPO_4 crystal The wavegnide was fabricated by using a femtosecond laser, and the fabrication process was optimized. In our experiments single mode propagation was observed at optimal wavegnide width of 14.5 μm and quasi-phase matching wavelength of 1064 nm. The second-harmonic conversion efficiency of 39.8% can be achieved. |
