Pulse ampligication in SOAs with ultrafast gain-recovery times

In this talk, I present my results on detailed numerical and experimental study of Self-Phase Modulation (SPM) in semiconductor optical amplifiers (SOAs) with ultrafast gain-recovery times. These SOAs have a range of gain-recovery speed which is a function of drive current. At increased drive current, the amount of internal ASE in the SOA increases, which causes the small signal gain to saturate and reduces the gain-recovery time. Understanding pulse amplification in these SOAs is important for optimizing the performance of SOA-based optical regenerators and wavelength converters.
Bring your lunch at the talk; we will offer the dessert!
