【摘要】 提出条形半导体激光器中稳态电过程和光波导过程及其相互作用的精确模型,并从电极电压算起得出阈值以上的电压电流分布和基模光场分布的相互影响和变化的计算机结果.指出简单的p-n结注入公式和任何固定形式的结电流分布假设对分析条形半导体激光器中的电过程和光波导过程都不适用,本文还探讨了光功率-注入电流特性出现扭折的机制和条件.更多还原

【Abstract】 The electrical and optical waveguiding processes and their interaction in stripe-geometrysemiconductor laser has been treated by an accurate model and the detailed self-consistnt com-puter results have been obtained.It is shown that the usual p-n injection current-voltage rela-tion and any imposed-fixedshaped injection current distribution should not be used as basesin analyzing waveguiding behavior in stripe-geometry semiconductor laser. The so-called self-focusing mechanism of the kink in the optical power-current characteristics has also been exa-mined.更多还原
