摘要	A Vertical-Cavity Surface-Emitting Laser has a resonant cavity (3,5) and an external cavity (6,15) formed as a monolithic structure, the external cavity being arranged to provide loss differences for different linearly polarised modes, the loss differences being arranged to provide an output with a stable polarisation state. Compared to the known polarisation stability techniques, this enables a stable polarisation output without the complexity of modification of the VCSEL structure, less sensitivity to small changes of injected current and temperature, and less need for the complex, non monolithic optical parts. Active polarisation control and stabilisation in the same device can be achieved by growing a polarisation dependent mirror on top of the VCSEL and by applying an external field to alter an optical length of the external cavity.
其他摘要	垂直腔面发射激光器具有谐振腔（3,5）和形成为单片结构的外腔（6,15），外腔被布置成为不同的线性极化模式提供损耗差异，损耗差异被布置为提供具有稳定偏振态的输出。与已知的偏振稳定性技术相比，这使得能够实现稳定的偏振输出，而不需要修改VCSEL结构的复杂性，对注入电流和温度的微小变化的灵敏度较低，并且对复杂的非单片光学部件的需求较少。通过在VCSEL顶部生长偏振相关镜并且通过施加外部场来改变外腔的光学长度，可以实现在同一装置中的主动偏振控制和稳定。
