All-optical demultiplexing of 8x2.5-Gb/s pseudorandom OTDM data stream using nonlinear optical loop mirror

摘要

We demonstrate an optical time division demultiplexing from 8 $MUL 2.5 Gb/s pseudorandom data stream using a nonlinear optical loop mirror, or nonlinear fiber Sagnac interferometer switch. To ensure good extinction ratio of the demultiplexed signal, some experimental results show it is necessary to adjust carefully the dc bias, modulation current, compression fiber length and switching width and synchronous between the data and control pulses.
