We demonstrate simultaneous demultiplexing, data regeneration and clock recovery at 10Gbits/s, using a single semiconductor optical amplifier-based nonlinear-optical loop mirror in a phase-locked loop configuration.
We investigate collisions between solitons in a lossless two-channel wavelength-division multiplexed system with strong dispersion management. Numerical results show that the net frequency shift that is due to interchannel collisions is at least 1 order of magnitude smaller than predicted by adiabatic theories. A modified theoretical analysis is presented… (More)
We present a numerical analysis that indicates that a 3 x 3 nonplanar fused-fiber coupler can be used to inhibit longitudinal mode hops in a narrow linewidth unidirectional ring fiber laser. We also give preliminary experimental data that support our numerical analysis.
A unidirectional erbium fiber laser incorporating a novel LiNbO(3) overlay fiber-optic bandpass filter is demonstrated. By applying index-matching oils of different refractive indices to the surface of the overlay filter, we could tune the operating wavelength of the laser from 1531 to 1556 nm while maintaining a bandwidth of less than 0.2 nm (resolution… (More)
