Demultiplexing of arbitrarily polarized 100 Gb/s words using a twisted fiber nonlinear optical loop mirror

Summary form only given. We demonstrate a 100 Gb/s demultiplexer for data with arbitrary input states of polarization using a polarization insensitive, two-wavelength, nonlinear optical loop mirror (2/spl lambda/ NOLM). The device uses 450 m of twisted fiber to achieve polarization sensitivity <0.5 dB, timing window /spl sim/5.5 ps, contrast ratio >15 dB, and Q-parameter >15. Our demultiplexer combines the 2/spl lambda/ NOLM with a local laser and synchronization circuit based on a phase-locked-loop and an acousto-optic modulator and grating in the laser.
