摘要	A new VCSEL design is presented to achieve high output power and high brightness with a strong selection of a linear polarization state in high speed pulsing operation. Higher output power is achieved by including multiple gain segments in tandem, in the gain region. To achieve single mode operation with high output power, an extended cavity three reflector design is presented. High degree of polarization selectivity is achieved by a linear grating deployed with the third reflector, such that lasing is allowed only in a preferred linear polarization state. A polarization selective reflector including a linear grating is designed to impart strong polarization selectivity for a preferred linear polarization state. The polarization selective reflector used as the third reflector in an extended cavity VCSEL device, exhibits strong polarization selection for a preferred linear polarization state during high speed pulsing including in the gain switching resonance regime.
其他摘要	提出了一种新的VCSEL设计，以实现高输出功率和高亮度，并在高速脉冲操作中强烈选择线性偏振态。通过在增益区域中串联包括多个增益段来实现更高的输出功率。为实现高输出功率的单模操作，提出了一种扩展腔三反射器设计。通过与第三反射器一起部署的线性光栅实现高度偏振选择性，使得仅在优选的线性偏振状态下允许激光发射。包括线性光栅的偏振选择反射器被设计成对优选的线性偏振态赋予强偏振选择性。用作扩展腔VCSEL器件中的第三反射器的偏振选择反射器在高速脉冲期间表现出对于优选线性偏振态的强偏振选择，包括在增益切换谐振区域中。
