We experimentally show that the efficiency of dispersive wave generation by a four-wave mixing cascade is strongly affected by pump frequency detuning. Results are explained using both time and frequency domain descriptions.
We experimentally show that the pump frequency detuning strongly affects the efficiency of dispersive wave generation by cascaded four-wave mixing. We explain our results in terms of higher-order soliton compression of the input beat signal.
We theoretically and experimentally show that fiber-optic analogues of event horizons can be explained by cascaded four-wave mixing of monochromatic continuous waves. Experiments performed with pulsed and continuous wave lasers are in excellent agreement.
Conventionally dispersive wave (DW) emission in nonlinear fiber optics is described in the time-domain as the resonant amplification of a linear wave propagating in-phase with a soliton pump [1]. Recently, however, a complementary frequency-domain description has been presented, which identifies the nonlinear origins of the process as phasematched cascaded four-wave mixing [2]. This new theory predicts...
We investigate the statistics of the gain fluctuations of a Raman fiber amplifier pumped with a temporally incoherent pump. We present a simple theory whose predictions are in good agreement with our numerical and experimental results.
