摘要

实验研究了InGaAsP/InP多量子阱脊波导激光二极管在较宽温度范围内的串联电阻，适用于法布里-珀罗和分布反馈型激光器。从串联电阻的温度依赖性中发现，尽管半导体体电阻也是脊波导激光器串联电阻的重要组成部分，但串联电阻主要由异质阻挡电阻定义。研究了激光串联电阻对其性能特性的影响。理论预测的串联电阻与激光器最大工作功率之间的强相关性得到了实验证实。讨论了降低串联电阻的方法。

Series resistance and its effect on the maximum output power of 1.5 /spl mu/m strained-layer multiple-quantum-well ridge waveguide InGaAsP lasers

The series resistance of InGaAsP/InP Multiple Quantum Well ridge waveguide laser diodes is investigated experimentally over a wide temperature range for both Fabry-Perot and Distributed Feedback type lasers. From the temperature dependence of the series resistance is found that it is defined mostly by the resistance of heterobarriers, although the semiconductor bulk resistance is also found to be a substantial part of ridge waveguide laser series resistance. The effect of the laser series resistance on its performance characteristics is investigated. The theoretically predicted strong correlation between the series resistance and laser maximum operating power is confirmed experimentally. The ways of reducing of series resistance are discussed.
