All-optical 40 Gb/s 3R regeneration assisted by clock-extraction based on a passively mode-locked quantum-dash Fabry-Pérot laser

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.
