A plurality of incident light beams are parallelly propagated in a thin film optical waveguide. Simultaneously, a surface acoustic wave is propagated in said thin film optical waveguide, and the plurality of incident light beams are selectively successively guided to a light output part by the acousto-optic...http://www.google.es/patents/US4595253?utm_source=gb-gplus-sharePatente US4595253 - Parallel-to-serial conversion of optical data using acousto-optical diffraction
