Free Space Optical Interconnects for Data Routing, Switching, and Processing
نویسنده
چکیده
A procedure for designing and fabricating holograms which are used for generating free space optical interconnections is described. The design process uses the Gerchberg-Saxton algorithm and a random search (simulated annealing) method. Fabrication is performed by electron beam lithography and acetone etch of a polymethyl methacrylate film. The use of holograms fabricated by this method in an optoelectronic processing module is discussed. The interconnect patterns required to implement switching and data processing devices are discussed, including a crossbar switch, an adder, and a multiplier. Holograms which implement these interconnect patterns have been fabricated.
