Integrated optical structure for multiplexing or demultiplexing optical waves, has optical coupling elements with input optical guide or output network forming beam of phase wave propagation through optical network

摘要

The integrated optical system has a layer with optical coupling elements (6). There is an input optical guide (5) and optical guide (7) forming a network (8) in parallel. The optical coupling element is at the optical input and has a transformer (23) to attenuate the amplitude or modify the phase and partially stop wave propagation from the input to the optical guide network.
