SINGLE BEAM SIDE DEFLECTOR, COUPLER CONTROL AND APPLICATIONS TO WAVE LENGTH DEMULTIPLEXERS AND OPTICAL ANTENNA FEEDERS

Integrated optical circuits are miniaturized optical systems made up of various components that are manufactured on wafers using deposition, material growth, and lithographic techniques similar to those used in microelectronics. By means of these techniques, channels formed by materials with different dielectric constant (waveguides or waveguides) are manufactured in the wafer that allow the light to be guided and manipulated through the plane of the wafer with low losses of optical power. On the other hand, couplers are part of the vast majority of integrated optical subsystems such as modulators, receivers, demultiplexers or filters and are therefore components of great practical application in many applications. The present invention solves the problems of current devices through a system based on a diffraction grating that efficiently couples the light, by means of diffraction, from a channel waveguide to a film waveguide that keeps the light confined in the wafer plane.
