Abstract

All-optical active mode-locking (AOAML) and clock recovery operations have been demonstrated by means of external injection of a train or stream of pulses, say control pulses, into a fiber loop containing a gain medium and a nonlinear medium such as long spans of dispersion-shifted fibers (DSF) or semiconductor optical amplifiers.^1–4 Cross-phase modulation combined with a dissipative nonlinearity, or even without it, provided the basic mechanism that permitted the locking of the cavity longitudinal modes up to 40 GHz.^4,5
