Abstract:
An optical transmission system, comprising:a source for transmitting an input optical signal; an optical array having a primary input for receiving said optical signal; a plurality of delay lines, each said delay line having an input, an output, and a predetermined optical path length; an optical splitter coupled to said primary input, for splitting said input optical signal into a plurality of delay line signals, each of said delay line signals being input to one corresponding delay line input and each said delay carries its respective delay line signal to a destination point located at said delay line outputs; means for producing a plurality of control signals, utilizing orthogonal code modulation, to control the modulation of an optical wave component of each said delay line signal; and means for modulating each said delay line optical wave component according to said corresponding control signal; and wherein said means for producing a plurality of control signals comprises a processor for receiving electrical signals derived from output optical signals sampled at said delay line outputs, and for generating therefrom each one of said control signals by independently determining an optimal modulation value of said optical wave component of each of said corresponding delay line signals.
