摘　　要：通过Lang-Kobayashi速率方程发现并研究了光反馈弧边六角微腔激光器的稳态-准周期态切换现象,分析了反馈速率和偏置电流对该切换现象的影响,并通过分岔图分析了此切换现象产生的原因。结果表明,在高偏置电流、长腔反馈情况下,更容易出现稳态-准周期态切换的现象。最后对比分析了该切换现象与其他激光器出现的类似现象的区别。We observed and investigated the phenomenon of switching between stable state and quasi-periodic state in circular-side hexagonal resonator microcavity laser with optical feedback by the Lang-Kobayashi rate equation.The influences of feedback rate and bias current on the switching between two dynamical states are analyzed,and the reason for this switching phenomenon is analyzed by bifurcation diagrams.The results show that the phenomenon of switching between these two states is more likely to occur under the conditions of high bias current and long external-cavity feedback.Finally,the difference between this switching phenomenon and the similar phenomenon of other lasers is compared and analyzed.
