中文摘要： 1550nm-VCSELs相对于边发射激光器具有自身独特的优势，在光通信、光信息处理、并行光互连等领域应用前景广阔。目前对其多种外部扰动下的偏振开关及偏振双稳特性的研究尚有许多基础性科学问题亟待解决，这在一定程度上阻碍了基于复杂环境下1550nm-VCSELs偏振开关及偏振双稳特性的相关应用技术的研发。本项目将构建合理描述多种外部扰动下1550nm-VCSELs偏振开关及偏振双稳行为的理论模型；系统研究各种外部扰动之间的相互作用规律及复杂环境下1550nm-VCSELs的偏振开关及偏振双稳行为的精确调控技术；基于复杂环境下1550nm-VCSELs的偏振双稳特性，探索实现10GHz高速全光触发运行技术。该项目的实施，有望在多种外部扰动下1550nm-VCSELs偏振开关及偏振双稳特性的基础性研究方面获得突破，并研发出具有自主知识产权的10GHz高速全光触发运行获取技术。

英文摘要： Due to their some unique virtues compared with edge-emitting semiconductor lasers, 1550nm vertical-cavity surface-emitting lasers (1550nm-VCSELs) have wide application prospects in different fields such as optical communication, all-optical signal processing, parallel optical interconnection and so on. At present, there still exist in many basically scientific problems needed to be solved during the investigation on the polarization switching and bistability of 1550nm-VCSELs under various external disturbances , which to some extent hinders the research and development of related application techniques. In this project, at first, a reasonable theoretical model will be constructed to describe the polarization switching and bistability of 1550nm-VCSELs various external disturbances.Secondly, systematic investigations on the effect between various external disturbances on the polarization switching and bistability of 1550nm-VCSELs will be accomplished,and accurate controlling of polarization switching and bistable behavior will be realized experimentally in the complex external environment. Finally, based on the polarization bistable 1550nm-VCSELs in the complex external environment, 10GHz-repetition-frequency all-optical flip-flop operations will be on how to achieve. By carrying on this project, we hope to achiev
