title: Pulse evolution and phase-sensitive amplification in silicon waveguides.
abstract: We provide an analytic solution for pulse propagation and phase-sensitive amplification in silicon waveguides in the regime of strong two-photon absorption (TPA) and significant free-carrier effects. Our analytic results clearly explain why and how the TPA and free carriers affect the signal gain. These observations are confirmed with numerical modelling and experimental results.
