Multielement Integrated Optical Devices Based on High-Refractive-Index Materials

摘要

The effect of an additional high-refractive-index layer on the properties of planar waveguides for multielement integrated optical devices is considered. The conditions for highly efficient coupling (self-coupling) upon beam propagation from the three-layer to the four-layer region are determined. Technological recommendations for the production of optical waveguide beam splitters with an increased number of output elements are given.
