We experimentally investigate the nonlinear dynamics of two mutually coupled 1550 nm multi-transverse-mode vertical-cavity surface-emitting lasers (VCSELs). The results show that, through continuously varying the coupling coefficient, the -polarization fundamental transverse mode and the -polarization first-order transverse mode in both VCSELs can be driven into period one, period doubling, multi-period, and chaos states. When the two mutually coupled VCSELs are simultaneously operating in the periodic state, localized synchronizations between the corresponding modes are observed. Moreover, mappings of dynamical states for typical transverse modes of the two mutually coupled VCSELs in the parameter space of the frequency detuning and coupling coefficient are specified.
我们通过实验研究了两个相互耦合的1550纳米多横向模式垂直腔面发射激光器（VCSEL）的非线性动力学。结果表明，通过连续改变耦合系数，两个VCSEL中的 - 偏振基横模和 - 偏振一阶横模可以被驱动到周期一、倍周期、多周期和混沌状态。当两个相互耦合的VCSEL同时处于周期状态时，观察到相应模式之间的局部同步。此外，还给出了在频率失谐和耦合系数参数空间中两个相互耦合VCSEL典型横模的动态状态映射。
