The objective of this project is to study the effects of polarization modedispersion on fiber communication systems. Polarization mode dispersion (PMD)is caused by random birefringence of optical fibers. As the bit rate per channelis reaching tens of gigabytes per second, PMD has become a major limiting factor on the system performance. The awardee will study the effects of PMD on both linear and soliton communication systems. In particular, he will investigate the probability distribution of the differential group delay for various birefringence models as a function of arbitrary fiber length in a linear transmission system. He also plans to examine the combined effects of PMD and weak nonlinearity on the statistics of the transmissionspectrum measured through a polarizer at the output of a test fiber. In addition, he will assess the effects of PMD on a soliton communication system.He will examine the statistics of PMD-induced timing jitter, polarizationfluctuations and dispersive radiation, and estimate limitations imposed by PMD on soliton transmission. These problems are different but inter-related. The results of these studies will provide theoretical guidance on various aspects of communication system design. This project studies the effects of polarization mode dispersion (PMD) on fiber communication systems. This is a phenomenon that degrades the performance of optical fiber communication systems. It occurs randomly along optical fibers, changes with time and is hard to control. Therefore it is a major limiting factor for the performance of optical telecommunication systems. The work will directly address the realistic problem of PMD effects on current fiber communication systemsthrough the develoment and analysis of mathematical models and will thus lead to design recommendations and performance bounds for such systems

本计画的目的是研究偏振模色散对光纤通讯系统的影响。偏振模色散（PMD）是由光纤的随机双折射引起的。随着每信道的比特率达到每秒几十千兆字节，偏振模色散已成为限制系统性能的主要因素。获奖者将研究偏振模色散对线性和孤子通信系统的影响。特别是，他将调查的概率分布的差分群延迟的各种双折射模型的任意光纤长度的函数在线性传输系统。他还计划研究偏振模色散和弱非线性对通过偏振器在测试光纤输出端测量的透射光谱统计数据的综合影响。此外，他将评估PMD对孤子通信系统的影响，研究PMD引起的定时抖动、偏振波动和色散辐射的统计，并估计PMD对孤子传输的限制。这些问题各不相同，但又相互关联。这些研究结果将为通信系统设计的各个方面提供理论指导。本计画主要研究偏振模色散对光纤通讯系统的影响。这是一种降低光纤通信系统性能的现象。 它沿光纤沿着随机发生，随时间变化，难以控制。 因此，它是光通信系统性能的主要限制因素。通过建立和分析数学模型，直接解决PMD对当前光纤通信系统影响的现实问题，从而为此类系统提供设计建议和性能界限
