摘要：In N×N optical couplers, such as are used in local area networks and backplanesof telecommunications and computer equipment, which use BRAGG volume diffractionmeans to couple light beams between the inputs and outputs, the number of gratings isreduced by means of so- called \"grating degeneration\" one grating can be shared by atleast two wave pairs at the same time. In order to achieve this reduction, the directions oflight waves in the dielectric slab (or the lateral positions of fibre ends) are suitablearranged. In other embodiments, a reduced number of gratings is achieved by using a\"sandwiched\" structure which uses multi-layered dielectric slabs. Both embodiments maybe combined in the one coupler.
