Class Information
Number: 372/96
Name: Coherent light generators > Particular resonant cavity > Distributed feedback
Description: Subject matter in which the feedback structure comprising the resonant cavity is distributed through and integrated with the active medium of the laser and is created by substantially time constant, spatially periodic perturbations in the transmission characteristics of the medium along the length thereof, which may take the form of variations in the gain, index of refraction, propagation constant, or other parameter of the medium.
