COMPLEX ANGLE OF INCIDENCE FOR PLANAR OPTICAL WAVE-GUIDE ANALYSIS

We propose the concept of an incident angle in the form of complex num ber and analyse planar optical waveguides by applying the concept. The complex angle of incidence is concerned with the modelling of prism-g ap-waveguide structures. It is shown that, when optical waveguides are analysed by means of the transfer matrix method, the proposed concept enables us to rnd solutions faster and more accurately than by using the method utilizing the leaky structure.
