Paper Abstract

We have experimentally investigated supercontinuum generated by using different pulse dynamics patterns as the pump pulses. These patterns, which include conventional mode-locked single pulse, condensed phase pulses and pulsed bunches, were all directly produced from a mode-locked erbium-doped fiber laser based on a multi-layer graphene saturable absorber. The strong third-order optical nonlinearity of graphene and all fiber cavity configuration led to the multi-pulses operation states at a low pump power. A flat supercontinuum with 20-dB width of 550 nm from 1200 nm to 1750 nm have all been obtained by seeding the amplified conventional mode-locked single pulse and condensed phase pulses into a segment of photonic crystal fiber. On the other hand, experimental results also show that the pulsed bunches was not conducive to form a flat supercontinuum.
