A high-speed demultiplexer based on a nonlinear optical loop mirror with a photonic crystal fiber

A 50-m-long photonic crystal fiber with zero-dispersion wavelength at 1552 nm is used as the nonlinear medium in a nonlinear optical loop-mirror-based demultiplexer. The successful demultiplexing of an 80-Gb/s optical time-division multiplexing signal transmitted through an 80-km span of standard single-mode fiber and the error-free demultiplexing from 160 Gb/s are achieved.
