摘　　要：制备并测试了 II 型中红外带间级联激光器制备的器件在脉冲和连续工作模式下最高工作温度分别为275K和226K.80K下器件激射波长为3.8μm左右阈值电流密度约17A/cm2.对器件在连续工作模式下的自加热效应进行了分析并利用有限元方法模拟了器件连续工作时的温度分布图.分析和模拟结果均表明自加热效应是限制器件连续工作温度的重要因素.提高散热性能将是进一步提升器件工作温度的有效手段.In this paper InAs based type II interband cascade lasers operating at the mid infrared range were fabri cated and characterized. The maximum operating temperatures under pulsed and continuous wave (CW) operating mode are determined to be 275 K and 226 K respectively. The threshold current density is around 17 A/ cm2 at 80 K with an emission wavelength of approximate 3. 8 μm . We analyzed the self heating effects under CW mode and further simulated the temperature contour by the finite element method. The results indicate that the self heating effect is a critical factor that limits the operating temperature under CW mode for our devices. Further optimization of the heat dissipation performance would be an effective way to raise the operating temperature of these devices.
