摘要

在连续波(CW)和脉冲条件下，基于外延集成InP分布布拉格反射器(DBR)制备并评价了长波垂直腔激光器(VCL)。我们得出结论，对于InP-DBR-down配置，高温性能受到底部反射镜的导热性的限制。连续波和脉冲状态下的最高工作温度分别为17/spl℃和101/spl℃，表明连续波具有很强的自热性。为了研究在其他安装结构中改进性能的前景，我们对传热问题进行了二维有限元分析。建议将AlGaAs/GaAs DBR安装在最靠近散热器的地方，可以实现与所谓的双熔接vcl相当的性能。

Temperature-dependent performance of 1.55 /spl mu/m vertical-cavity lasers with InGaAsP/InP bottom mirror

We have fabricated and evaluated a long-wavelength vertical-cavity laser (VCL) based on an epitaxially integrated InP distributed Bragg reflector (DBR) under continuous wave (CW) and pulsed conditions. We conclude that, for an InP-DBR-down configuration, the high temperature performance is limited by the heat conductivity of the bottom mirror. The highest operating temperature for CW and pulsed condition is 17/spl deg/C and 101/spl deg/C respectively, indicating a substantial self-heating for CW. To investigate the prospect for improved performance in other mounting configurations, we have applied a two-dimensional finite element analysis to the heat transfer problem. It is suggested that for top-side-down mounting with the AlGaAs/GaAs DBR closest to the heat sink, a performance comparable to that of so called double-fused VCLs could be possible.
