中文摘要： 1550nm-VCSELs相对于边发射半导体激光器具有自身独特优势，在光通信、光信息处理、并行光互连等领域应用前景广阔。目前对其非线性动力学行为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1550nm-VCSELs的相关应用技术的研发。本项目将构建合理描述1550nm-VCSELs非线性动力学行为的理论模型，系统研究多种外部扰动下1550nm-VCSELs的动力学行为，获得在不同系统参数空间动力学状态的分布图谱；实验上实现对各动力学状态的准确调控；基于光注入1550nm-VCSELs单周期振荡，探索通过利用频率为单周期振荡频率1/n(n为整数)的低频微波对其进行频率锁定以期获得满足RoF系统副载波要求的60GHz光毫米波的技术方案。该项目的实施，有望在1550nm-VCSELs非线性动力学的基础研究方面获得突破，并研发出具有自主知识产权的60GHz高性能光毫米波获取技术。

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 nonlinear dynamics of 1550nm-VCSELs, 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 nonlinear dynamics of 1550nm-VCSELs, and systematic investigations on the dynamics of 1550nm-VCSELs under various external disturbances will be accomplished. As a result, the distribution maps of the dynamical states of 1550nm-VCSELs in different spaces of systemic parameters will be obtained. Secondly, accurate controlling of diversely dynamical states will be realized experimentally. Finally, based on the period-one oscillation state of 1550nm-VCSELs under optical injection, a novel frequency locking technique scheme, by which the period-one frequency is locked through introducing a low frequency RF source whose operating frequency locates at the nth sub-harmonic of the per
