Optical waveguides can be fabricated in the nonlinear material potassium titanyl arsenate (KTiOAsO4) using ion exchange in a mixed RbNO3/Ba(NO3)2 melt. The guiding properties of such waveguides were measured and the variation of these properties with changes in processing conditions was investigated. © 1996 American Institute of Physics.
