Abstract-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.
Supercontinuum (SC) generation is demonstrated in a photonic crystal fibre (PCF) at 1550 nm with pulse widths of 0.3 to 2.5 ps. Subsequent band-pass filtering of the generated SC spectrum enables the realisation of an optical clock frequency translator continuously tunable up to the L-band.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
