Wavelength tunability of an all-optical clock recovery operation based on a quantum-dash mode-locked Fabry-Pérot laser diode is experimentally investigated. Synchronization of the device to the injection of 40-Gb/s nonreturn-to-zero (NRZ) incoming data is assessed by analyzing both the carrier-to-noise ratio and the linewidth of the 40-GHz beat-tones measured at the mode-locked laser output. Under...
Experimental measurements on a quantum dash mode-locked Fabry-Perot laser are presented. Its potential for clock recovery at 40 Gb/s in an all-optical 3R regeneration with an NRZ-to-RZ format conversion and wavelength offset of 23 nm is demonstrated.
