论文部分内容阅读
论文可以分为两大部分。第一部分讨论了半导体激光器的分配噪声对单模光纤和多模光纤通信系统的影响,特别是对由其产生的模式噪声的分析。第二部分讨论了入射条件对模式噪声的影响。现在使用的半导体激光器一般部是纵模的。由于激光器的量子效应,光功率在各个纵模之间的分配不断地变化,造成单个纵模的涨落噪声很大。这种分配噪声只是当传输对各纵模
Papers can be divided into two parts. The first part discusses the influence of the distributed noise of semiconductor lasers on single-mode optical fiber and multi-mode optical fiber communication systems, especially the analysis of the mode noise generated by them. The second part discusses the impact of incident conditions on the pattern noise. The semiconductor lasers currently used are generally longitudinal mode. Due to the quantum effect of the laser, the distribution of optical power between the individual longitudinal modes is constantly changing, resulting in large fluctuations of the single longitudinal modes. This distribution of noise is only when transmitted to each longitudinal mode
