Paper Abstract

We report the fabricated method of Rb/Ba ion-exchanged (KTiOPO4) KTP planar waveguides and the measuring result of photorefractive sensitivity and lattice constant change in the waveguides, and then report the ideal mol% ratio of Rb to Ba. The experimental results show that the photorefractive sensitivity is 1.2 - 2.3 multiplied by 10-10 cm2/J, which is independent of Ba ion content and annealed procedure, and the change of lattice constant, which decrease with increase the Ba ion content, is 0.42 - 0.25%.
