Noise Analyses of New Multi-quantum-well Passively Mode-locked Laser Diodes

对多量子阱被动锁模半导体激光器的噪声理论进行了系统的分析 ,并给出了半导体激光器腔内相位随载流子浓度变化的关系。研究表明 ,被动锁模半导体激光器 (MLLDs)的总噪声主要由散粒噪声、自发辐射放大噪声、频率调制噪声和量子噪声组成 ,分别由光场的振幅。

In this paper,the noise theory of monolithic multi-quantum-well passively mode-locked laser diodes (MLLDs) is discussed, and the phase variation curve with carrier population of MLLDs is found. Therefore, it is important to understand the dynamic theory of mode-locked laser diodes in order to reduce its noise for fibre-optic communication system.
