NOLM-based wavelength conversion with FBG band-pass filter for optical packet switching
Nonlinear-optical-loop-mirror-based wavelength conversion is studied in details. A set of two-phase-shifted Bragg gratings are introduced into the coverter, serving as a narrow band-pass filter to remove new frequencies generated by walk-off and to compensate the dispersion. Numerical simulations are performed to validate our method. The results show that the converted pulses after the filter are reshaped and, sometimes, even compressed.
