摘要	A method is disclosed in which the principle of phase-coupling is used to stabilize the polarization of laser radiation emitted by a plurality of phase-coupled vertical cavity surface emitting laser elements Due to a suitable coupling strength between adjacent VCSEL elements, the probability of polarization flips of VCSEL devices operated in the single mode region is zero or at least drastically reduced. Moreover, a VCSEL device is disclosed, comprising a polarization adjusting means for controlling the polarization direction of an arrangement of a plurality of phase-coupled VCSEL elements, wherein the polarization direction of each VCSEL element is substantially kept constant.
其他摘要	公开了一种方法，其中相位耦合的原理用于稳定由多个相位耦合的垂直腔表面发射激光器元件发射的激光辐射的偏振。由于相邻VCSEL元件之间的适当耦合强度，极化的概率在单模区域中操作的VCSEL器件的翻转为零或至少显着减小。此外，公开了一种VCSEL器件，包括用于控制多个相位耦合的VCSEL元件的布置的偏振方向的偏振调整装置，其中每个VCSEL元件的偏振方向基本上保持恒定。
主权项	A method of stabilizing the polarization of a vertical cavity surface emitting laser {VCSEL) device, comprising: providing two or more VCSEL elements capable of emitting substantially a single mode radiation of substantially the same wavelength and arranged to allow phase-coupling between the two or more VCSEL elements, and initiating emission of radiation by injecting current into the two or more VCSEL elements to produce phase-coupled radiation, wherein the polarization direction of each of the two or more VCSEL elements remains substantially constant during operation,
