摘要

我们提出了完全单片，单步生长，双极级联MQW垂直腔表面发射激光器(VCSELs)，速度为1.55 /spl mu/m，具有大于单位的差分量子效率。典型器件的阈值电流密度为1 kA/cm/sup 2/，阈值电压为3.2 V，连续波(CW)工作温度高达8℃。

Bipolar cascade 1.55 /spl mu/m VCSELs with >1 differential quantum efficiency and CW operation

We present completely monolithic, single-step grown, bipolar cascade MQW vertical-cavity surface-emitting lasers (VCSELs) at 1.55 /spl mu/m with greater-than-unity differential quantum efficiency. A typical device had a threshold current density of 1 kA/cm/sup 2/, a threshold voltage of 3.2 V, and demonstrated continuous wave (CW) operation up to 8 C.
