Abstract
Four-wave mixing (FWM) in semiconductor optical amplifiers (SOAs) has a large conversion efficiency,1 which is deleterious for wavelength-multiplexed systems, but can be advantageous for nonlinear applications such as frequency conversion.2 The spectral dependence of FWM is determined by the interband and intraband dynamics of the inverted semiconductor medium and, hence, FWM spectroscopy provides insight into the fundamental physics of the SOA. Here we study non-degenerate four-wave mixing (NDFWM) for pump-probe detunings up to 4 THz (35 nm) under conditions of high input pump and probe powers, such that the gain of the SOA is compressed by 3-12 dB. Previous reports of highly-NDFWM have shown symmetric3 and asymmetric4,5 spectral dependence of NDFWM for higher energy and lower energy mixing products (anti-Stokes and Stokes components, respectively). In this work we report symmetric detuning spectra, higher efficiency generation of the anti-Stokes component compared to the Stokes component, and no saturation of the power dependence of the mixing products for large detunings.
