Inverse model for ultrashort pulse amplification in semiconductor optical amplifiers

To describe ultrashort pulse amplification in semiconductor optical amplifiers (SOAs), several models have been developed that calculate the amplified output pulse as a function of the input. Because of the many processes at play in SOAs (band filling, carrier heating, spectral hole burning, two-photon absorption, and the associated free-carrier absorption), it is challenging to predict which input is needed to generate a targeted output. In this Letter, we construct a generic inverse SOA model that calculates the required input pulse including its shape and phase to obtain a desired output. This inverse model will enable a more efficient and well-targeted design of SOA-based photonic systems, while also allowing better quality and performance control.
