摘　　要：本文从外腔半导体激光器修正的速率方程出发,导出了在存体激光器的相位噪声,强度噪声的功率谱密度以及在直接电流调制下的C腔、强反馈可以在很大程度上降低半导体激光器的噪声。In this paper, power spectrums of phase noise, intensity noise and the CPR of external cavity semiconductor lasers are studied analytically based on the improved rate equations. The results can be used in semiconductor lasers with arbitrary amount of optical feedback. It is noticed that the short external cavity with strong optical feedback can dramatically reduce the noise in semiconductor lasers.
