We propose a semiconductor fiber laser incorporating a multi-channel nonlinear optical loop mirror for multi-channel all-optical signal processing. We perform mode-locking at different wavelengths using independent pump signals and demonstrate the application to all-optical clock recovery.
We demonstrate all-optical clock recovery with switchable wavelengths from 10 Gb/s RZ data using a semiconductor fiber laser that is mode-locked with a nonlinear optical loop mirror. The performance is independent of the data wavelength.
We discuss two fiber-based approaches for all-optical clock recovery. The first exploits the buffering capability of the temporal Talbot effect and the second is based on a fiber laser and nonlinear optical loop mirror.
