ABSTRACT:
A laser source provides a pulse that is subdivided and replicated into subpulses by a delay structure having a plurality of steps. Each of the subpulses is delayed by one of the plurality of steps and the amount that each subpulse is delayed is different than the others with respect to the pulse. The amount of each delay, and the consequent time delay produced, is greater than the duration of the pulse, which minimizes overlap between adjacent subpulses. The pulse may be transmitted through the delay structure or it may be reflected from the delay structure. Repetition rates of up to hundreds of THz or greater are achieved, and the system and method may be used in Time Division Multiplexing Systems. Information may be transmitted and carried by the subpulses by appropriate modulation techniques.
