SEMICONDUCTOR RADIATION COUPLING SYSTEM

摘要

A first array of laser diode devices are optically coupled by a diffraction grating comprising a plurality of spaced diffraction nodules in a grid array optically coupled to the devices. The light emitted from a device of the first array can pass through the grid array to a second device, reflect back to the emitting device in a Distributed Bragg Reflector (DBR) mode and deflect orthogonal to the emitted light optical axis to a third device in a Distributed Bragg Deflector (DBD) mode. The light from the second and third devices can be coupled to other laser diode devices by still further diffraction nodule arrays to produce phased-locked beams, beam steering of portions of the light and other effects.
