Dual-pump four-wave mixing in a distributed-feedback laser

Abstract

In this work, we demonstrate properties of a novel dual-pump four-wave mixing (DPFWM) scheme using a distributed-feedback (DFB) laser. The DFB laser acts as the mixing medium and one of the pump sources, while the second pump and the probe are injected. New experimental results are shown, including successful demonstration of the power laws of this scheme. We also show the effects of the wavelength detunings on the conversion efficiency and the signal-to-noise rations of the output signals.
