Conference on Optical Interconnections and Networks (1990. La Haya, Holanda).The phase profile of the wave scattered by a GRIN lens has been determined using the eikonal approximation for the scattering amplitude. This wave acts as the object wave in a holographic register to construct a GRIN holocoupler. Different geometries in the phase profile distribution are presented as functions of the taper shape.book parthttp://dx.doi.org/10.1117/12.20696http://proceedings.spiedigitallibrary.orgmetadata only access535EngineeringElectrical and ElectronicOpticsÓptica (Física)2209.19 Óptica Física
