To assess the capabilities of free-space optics in the context of wavelength-space switches, holographic beam steering and optical routing of ATM cells. To contribute to the design of high-fan-in/fan-out switch architectures and to demonstrate key sub-assemblies. Progress:This is a collaborative project with Cambridge University Engineering Department and University College Electronic Engineering Department with industrial support from British Telecommunications and Bell Northern Research. The project concerns the use of Spatial Light Modulators and associated technology in Wavelength Division Multiplexed (WDM) and Asynchronous Transfer Mode (ATM) systems. The role of Kings in the project is to assess the feasibility of the free-space optical interconnection envisaged in these systems.The majority of the work to date has concerned wavelength space switches. The system requirements have been identified and a survey made of the options for fan-in and fan-out optics. The results of an assessment of some preliminary designs are contained in a major report currently being completed. Similar studies have now been commenced in the context of an ATM switch demonstrator as well as studies of fundamental limits of this architecture. Our micro-optics technology has also been further developed. We have e-beam direct writewith field stitching to moderate accuracy (0.5-m) as well as RIE etching facilities in house. Using these facilities and the CMF at RAL we have demonstrated Fresnel multiple beam splitters designed using our Generalised Error Diffusion algorithm. We have also acquired Code V ray tracing software to aid us with the optical design of the systems.
