我们分析了垂直腔面发射激光器(VCSEL)的自旋操纵潜力，通过电操作和通过偏振光激发注入额外的自旋偏振载流子。当注入电流不超过阈值电流时，VCSEL的输出极化可以很容易地由光学注入载流子的自旋取向来控制。
We analyze the potential for the spin manipulation of vertical-cavity surface-emitting lasers (VCSELs) by operating them electrically and injecting additional spin-polarized carriers by polarized optical excitation. The output polarization of the VCSELs can be easily controlled by the spin orientation of the optically injected carriers when the injection current does not exceed the threshold current.
