Integrated-optical head on lithium niobate

The practical feasibility of designing an integrated optical head for disk holographic memory has been studied. Computation procedure for topology design of refractive waveguide lenses and planar optical systems has been developed. Fundamental factors causing the bit rate limitation when recording the information on the optical disk of a planar head have been revealed. A prototype of a 12-bit head has been fabricated and experimentally investigated.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.
