Paper Abstract

A scheme for all-optical repetition rate multiplication of pseudorandom bit sequences (PRBS) is demonstrated with a precision delay feedback loop cascaded with a terahertz optical asymmetric demultiplexer (TOAD)-based power equalizer. Its feasibility has been verified by experiments, which show a multiplication for PRBS at cycle 2^71 from 2.5 to 10  Gb/s . This scheme can be employed for the rate multiplication of a much longer cycle PRBS at a much higher bit rate over 40  Gb/s if the time-delay, the loss, and the dispersion of an optical delay line are all precisely managed.
