从速率方程出发对双区共腔（ｃｏｍｍｏｎ－ｃａｖｉｔｙｔｗｏｓｅｃｔｉｏｎ简称ＣＣＴＳ）光双稳激光器进行了精确的理论分析与计算，并对其稳态特性进行了实验研究和测试，得出了定量和定性的分析结果，同时还首次发现当激光输出高态时又出现了一次光双稳和开关效应。经研究确认是量子阱探测器的自电光效应。并提出一种可集成双逻辑功能显示的新型网络模型器件。 Starting from the rate equation, the accurate theoretical analysis and calculation of the common-cavitytwosection (CCTS) optical bistable laser are carried out. The steady-state characteristics of the system are experimentally studied and tested, and the quantitative and qualitative analysis As a result, it was also found for the first time that a light bistable and switching effect occurred again when the laser output was high. The research confirmed that the quantum well detector self-electro-optic effect. And proposes a new network model device that can integrate dual logic function display.
