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.
We demonstrate a mode-locked, multiwavelength erbium-doped fiber laser at 2.5 GHz with 25-GHz channel spacing and that is wavelength tunable from 1545 to 1558 nm. Stable, room-temperature operation is obtained by exploiting four-wave mixing in a length of highly nonlinear fiber. At a central wavelength of 1549.5 nm, we obtain 30 wavelengths within 3 dB and 46 wavelengths within 6 dB; the full-width...
