    摘要:

    通过MBE外延系统生长了1.3 μm的GaAs基InAs量子点激光器.为了获得更好的器件性能,InAs量子点的最优生长温度被标定为520 ℃,并且在有源区中引入Be掺杂.制备了脊宽100 μm,腔长2 mm的激光器单管器件,在未镀膜的情况下,达到了峰值功率1.008 W的室温连续工作,阈值电流密度为110 A/cm-2,在80℃下仍然可以实现连续工作,在50 ℃以下范围内,特征温度达到405 K.

    Abstract:

    GaAs-based 1.3 μm InAs quantum dot laser have been grown by MBE system. Under the optimized InAs quantum dots growth temperature of 520℃, and the methods of Be-doping in the active region are adopted for better device performance. With a ridge width of 100 μm and cavity length of 2 mm, the maximum output power of single facet without coating has reached up to 1008 mW under continuous wave (CW) operation at room temperature, and the threshold current density is 110 A/cm2. The QD lasers can still operate at continuous waves (CW) up to 80℃, and the characteristic temperature below 50℃ is as high as 405 K.
