Computer-generated guided-wave holography: application to beam splitting.
The use of guided-wave synthetic holograms in integrated optics is extended beyond the conventional Fresnel lens and Bragg grating technology. As an example, beam splitters based on Fourier-domain holograms are proposed as an alternative to the usual channel waveguide devices. We demonstrate fanout to six with +/-5% (+/-0.2-dB) uniformity error using a binary phase grating and fanout to eight with +/-20% (+/-0.8-dB) uniformity error using a multilevel grating.
