All optical clock extraction and demultiplexing in 4/spl times/10 GHz OTDM system

We report the experimental results of all optical clock extraction and demultiplexing from 4/spl times/10 GHz time division multiplexing signals. The wavelength of the input signal pulses is converted for demultiplexing with a mode-locked figure-eight laser as clock extraction unit. Each of the four channels is successfully demultiplexed with a semiconductor laser amplifier in a loop mirror.
