本文用半经典理论研究了强度负反馈(NIFB)半导体激光器的噪声性能,给出了AM噪声和FM噪声谱的表达式,指出NIFB不仅可以极大地抑制AM噪声,而且也可以适当地改变FM噪声。
In this paper, the noise performance of NIFB semiconductor laser is studied by semi-classical theory. The expressions of AM noise and FM noise spectrum are given. It is pointed out that NIFB not only can greatly suppress AM noise but also can change FM noise properly .
