Abstract
Abstract Ferroelectric liquid crystal spatial light modulators can be used to display high quality binary phase holograms, and incorporated into programmable free space interconnects. These are potentially highly efficient, and have advantages over conventional shutter based architectures. Such structures have applications in telecommunications and optical processing. In this paper a 16 channel ‘crossbar’ interconnect is presented. Hologram measurement indicates the crossbar will function with a high noise margin. Device nonuniformities cause distortion in the hologram replay and techniques to compensate for this are discussed. Optical throughput and DC balancing of the liquid crystal currently restrict the performance of the switch: Possible solutions to these problems are detailed.
