Spectrogram of Carrier Transient in Semiconductor Optical Amplifier with Dispersive Pump-Probe Spectroscopy

Spectrogram of carrier transient in semiconductor optical amplifiers (SOA) is of great significance for its input conditions and ensuring the quality of the output signal. As the carrier transient process usually happens in picosecond time scale, sub-picosecond temporal resolution is required to resolve this dynamic process. Therefore, the ultrafast pump-probe technology is introduced, and it requ...
