1. A time multiplexed opto-electronic signal control system for processing an optical input signal having a predetermined polarization, comprising:

  • an opto-electronic signal processing system comprising at least a first and a second signal processing channel, said first and second channel each being adapted to selectively receive said optical input signal and generate a respective channel optical output signal, each of said channels further comprising a plurality of relatively slow speed optical processing devices sequentially coupled together, each of said optical processing devices being adapted to be individually selectively controlled to cumulatively generate respective time-delayed channel optical output signals from each channel; and

    time multiplexing means for rapidly switching between respective ones of said signal processing channels to select an active channel to produce a control system output signal comprising sequential ones of active channel output signals and having a relatively short dead time between said sequential active channel output signals;

    each of said plurality of relatively slow speed optical processing devices in the non-active channel being adapted to be controlled independently of and concurrently with the operation of said optical processing devices in said active channel to establish an optical configuration to process the next sequential system output signal.
