Abstract
The planar waveguides are formed by He ion implantation on lithium nio bate and lithium tantalate crystals. The refractive index profiles in the waveguides are obtained and fitted. The He ion implantation result s in the decrease of indices in the barriers both for lithium niobate and lithium tantalate. In the region of guide, the profiles of the ext raordinary indices n(e) in two crystals are significantly different. T he probable reasons are discussed by use of O-16(alpha, alpha)O-16 3.0 45 MeV resonance reaction.
