摘要：

The first MeV hydrogen ion implanted waveguide in KTiOPO4 is reported. The planar optical waveguide in KTiOPO4 was fabricated by 1.0 MeV hydrogen ions to a dose of 2 x 10(16) ions/cm(2) at room temperature. The dark modes were observed by prism coupling. Both refractive index profiles before and after annealing show a typical barrier waveguide in KTiOPO4 formed by 1.0 MeV hydrogen ion implantation. After annealing at 200 degrees C for 30 min, a 0.4% decrease in the refractive index was observed. Loss is estimated to be less than 2.2 dB/cm.
