| 摘 要： | 为了提高980 nm垂直腔面发射激光器(VCSEL)列阵的整体性能,对列阵单元器件的分布布拉格反射镜(DBR)的反射率进行了优化.分析了DBR的反射率与阈值电流,输出功率及转换效率之间的关系,在维持较低阈值电流的前提下适当调节了N-DBR的反射率,使单元器件斜率效率得到了有效提高,进而改善了VCSEL列阵的整体输出特性...

| Abstract: | The reflectivity of a Distributed Bragg Reflector(DBR) was optimized to improve the output characteristics of a 980 nm Vertical-cavity Surface-emitting Laser(VCSEL) array.The relationship among the reflectivity of N-DBR,threshold current,output power and wall-plug efficiency was analyzed.Then,the reflectivity of N-DBR was adjusted to achieve higher slope efficiency in a relative low threshold current and to improve the overall output characteristics of the VCSEL array.After N-DBR reflectivity optimization,t... |
