Abstract

Measured gain spectra from InAs/InP (100) quantum-dot amplifiers have been analyzed with a quantum-dot rate-equation model. The amplifiers are fabricated to have a peak gain wavelength around 1700nm. Our comparison between measured and simulated gain spectra shows that two effects in the quantum-dot material introduce the 65 nm blue shift and change in shape that have been observed in the measured gain spectrum with an increase in injection current density from 1000A/cm2 to 3000A/cm2. The first effect is the shift from GS to ES, and the second effect the dot size dependent filling due to the dot size dependent escape rates.
