基于自旋反转模型, 研究了1550 nm垂直腔面发射激光器(VCSELs)在偏振保持光反馈下的非线性动力学特性. 结果表明:自由运行的1550 nm-VCSELs在电流增加的过程中,发生偏振转换所对应的电流值与内部参数的取值有关, 随着有源介质线性色散效应系数γa的增大, 偏振开关的转换点所对应的电流值将增加;偏振保持光反馈的引入将导致1550 nm-VCSELs中自由运行时的主导模(Y偏振模式)在不同电流下呈现不同动力学状态, 引起另外一个模式(X模式)激射, 两个模式的平均输出功率随电流的增加总体呈现增加的趋势,但伴随着起伏;反馈时间取不同值时, 1550 nm-VCSELs的输出随着反馈强度的增大经历倍周期、准周期或阵发混沌等多种通向混沌的演化途径.

Based on the framework of the spin-flip model, the nonlinear dynamics of 1550 nm vertical-cavity surface-emitting laser (VCSEL) subject to polarization-preserved optical feedback is theoretically investigated. The results show that for a free-running 1550 nm-VCSEL, the current value for polarization switching (PS) is affected seriously by the internal parameters; with the increase of the gain anisotropy coefficient γa, the corresponding current for PS increases. Due to the introduction of the polarization-preserved optical feedback, the dominant polarized mode (Y polarized mode) will display different dynamical states for different injection currents while the other mode (X polarized mode) may be excited. As a result, the average output powers of the two polarized modes increase with fluctuation with the increase of current. For different feedback times, the dynamic states of 1550 nm-VCSEL with polarization- preserved optical feedback maybe route into chaos via different evolution paths such as period doubling bifurcation, quasi-periodic bifurcation and intermittent chaos.-
