Measurements of gain and index dynamics in quantum dash semiconductor optical amplifiers

Ultrafast gain and index recovery of a 1.5um quantum dash amplifier after short pulse amplification is measured using pump-probe spectroscopy. The major part of the gain reduction is found to recover within a few picoseconds.
