Patent ID: 7260329

Claim:
Optical apparatus, comprising: a continuous-wave laser that outputs a continuous-wave driver signal; a codeword controlled optically actuated optical gate that comprises a plurality of serially coupled optically actuated optical switches that each comprise a signal port for receiving the driver signal, first and second output ports, and a pump port for receiving the codeword that selectively outputs the driver signal by way of either the first or second output ports as a function of the codeword; a demultiplexer that comprises a serially coupled chain of one bit optical delays coupled to data input ports of optically actuated optical switches that each comprise a pump port that receives the driver signal output by the gate, a data input port for receiving input data, a plurality of demultiplexing ports for outputting demultiplexed data, and a plurality of through ports for outputting the input data; a multiplexer that comprises a serially coupled chain of one bit optical delays coupled to data input ports of optically actuated optical switches that each comprise a pump port that receives the driver signal output by the gate, a data input port for receiving input data output by the demultiplexer, a plurality of multiplexing ports for receiving parallel data that is to be multiplexed, and a plurality of through ports for outputting multiplexed data.
