RT Book, Section T1 Phase profile determination for a holocoupler/GRIN medium system A1 Pedraza Velasco, María Lourdes De A1 Calvo Padilla, María Luisa AB 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.
