摘要
We present low-noise properties of a quantum box traveling-wave semiconductor laser amplifier (QB-TW-SLA) for the first time. The gain and population-inversion parameter of a quantum box structure are precisely expressed using density matrix theory. Due to sharp gain characteristics as well as small population inversion parameter, dominant two-beat noises were found to be significantly reduced in the quantum box semiconductor laser amplifier, even in solitary device without a narrow bandpass filter, and the noise figure can be reduced to 3.5 dB.
