Popis: In this work, a method for evaluating the radiation losses of abrupt transitions in planar optical waveguides is presented. We analyze optical discontinuities due to geometrical changes and/or variations of the refractive index profile of the waveguides. The modal matching technique is used to evaluate the radiation, as well as the reflection and transmission coefficients. Both symmetrical and non-symmetrical planar waveguides are considered. Step and graded index profiles are taken into account. Results of radiation losses are given.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
