Regeneratively modelocked dual-wavelength soliton-pulse fibre-optical parametric oscillator in C- and L-bands

A self-starting regeneratively modelocked fibre-optical parametric oscillator that utilises four-wave mixing in a highly nonlinear fibre together with intra-cavity soliton formation to generate tunable, dual-wavelength picosecond pulses at 10 GHz rate simultaneously in the C- and L-bands, is demonstrated, believably for the first time. An electroabsorption-modulator-based optoelectronic oscillator is used as an ultra-low-jitter pump source that enables, by means of direct feedback injection locking, a significant reduction of the timing jitter of the obtained pulses.
