Abstract
An apparatus for controlling cycles of optical pulse streams based on a time correlation is disclosed. The feedback optical pulses and the input optical pulses are subjected to a time interleaving so as to make them not overlapped together, and then they are subjected to a time correlation, thereby considerably reducing the polarized beam dependence of the input optical pulse streams. The apparatus includes a clock generating means for generating clocks, and an optical pulse generating means for receiving the clocks from the clock generating means to generate optical pulses in synchronization with the pulses of the clock generating means. An input optical pulse distributing means distributes the feedback optical pulses of an output optical pulse distributing means, and distributes the optical pulses of the optical pulse generating means. A time correlation means correlates the time of optical pulses of the input optical pulse distributing means, and an optical pulse transferring/processing means amplifies and filters the optical pulses of the time correlation means to attenuate them. An output optical distributing means distributes the optical pulses of the optical pulse transferri…
