We demonstrate that polarization control in combination with the geometrical shape affects wave chaos phenomena in vertical-cavity surface-emitting lasers (VCSELs). In a grating-polarization-stabilized VCSEL, we demonstrate wave chaos in one polarization mode and a transition from wave chaos to regular behavior in the other orthogonal polarization mode. We quantify the amount of chaoticity via the Brody nearest-neighbor distribution. Comparing with a reference VCSEL without a surface-grating, we explain these results and their injection current dependence by the surface-grating-induced mode selection and a change in the effective resonator shape.
我们证明了在垂直腔面发射激光器（VCSEL）中，偏振控制与几何形状的结合会影响波混沌现象。在光栅偏振稳定的 VCSEL 中，我们在一个偏振模式中演示了波混沌，并在另一个正交偏振模式中演示了从波混沌到规则行为的转变。我们通过 Brody 最近邻分布来量化混沌程度。与没有表面光栅的参考 VCSEL 相比，我们通过表面光栅引起的模式选择和有效谐振腔形状的变化来解释这些结果及其与注入电流的关系。
