Development of a tantalum pentoxide Luneberg lens

The development of a tantalum pentoxide Luneburg lens for collimating the beam entering an integrated optical wavelength demultiplexer involved improvement of the deposition mask profile, reduction of surface scattering by underlaying the lens, reduction of edge scattering by shims under the mask, and prediction and measurement of TE - TM polarization aberration. The polarization aberration significantly affects the demultiplexer system design.© (1982) COPYRIGHT SPIE--The International Society for Optical Engineering.
