摘　　要：借助于SV-32低温恒温器及LD2002C5 VCSEL测试系统,对内腔接触式氧化物限制型垂直腔面发射激光器进行了变温实验研究,测得在-10℃～70℃温度范围内,器件输出光功率、电压、斜率效率、发射波长和阈值电流随温度变化的实验曲线,并结合不同温度下VCSEL反射谱和增益谱的模拟结果,对实验曲线进行了很好的分析和解释.估算了连续工作状态下研制的InGaAs/GaAs垂直腔面发射激光器内部温升值,而且还得到了现有工艺条件下满足最低室温工作阈值的谐振腔谐振波长与增益谱峰值波长.The temperature characteristics of intra-cavity contacted oxide-confined Vertical Cavity Surface Emitting Lasers(VCSELs)have been investigated by using the SV-32 cryostat and LD2002C5 test system.Some experimental cirves of output light-power,slope efficiency,lasing wavelength and threshold current as a function of temperature from-10℃ to 70.1℃ have been measured.In combination with the simulated results of the reflective spectrum and the gain spectrum at different temperatures,the measurement results have been amalyzed and explained.The risen temperature of InGaAs/GaAs oxide-confined VCSEL we fabricated can be estimated.The suitable relationship between the gain peak wavelength and the cavity resonance wavelength has also been achieved,which the minimum threshold current occurs at room temperature.
