Abstract / Description of output

All-optical switching at power levels down to 4(mu) W using the large thermal dispersive nonlinearity present in nematic liquid crystals is presented. Parallel operation is demonstrated in the form of a 15 X 15 array memory, and design criteria for three-port logic operation are considered with regard to circuitry requirements such as gain, speed, and fan-out. The implementation of an all-optical flip-flop consisting of coupled three-port logic gates is also described.
