提出了一种集成双波导（ITG）激光器，该激光器具有用于激光振荡的有源波导和光输出的外波导，可作为集成光学激光器或新型半导体激光器，并对其性能进行了理论和实验研究。以AlGaAs多异质结构的形式构建了ITG激光器，并在室温下通过光泵浦和电流注入获得了其初步特性。采用反向溅射法制备了有源波导的端镜。通过分析预测了轴向模式的选择性，并进行了实验观察。
An integrated twin-guide (ITG) laser which has an active waveguide for laser oscillation and an external waveguide for the light output is proposed as an integrated-optics laser or as a new semiconductor laser, and its properties are investigated theoretically and experimentally. ITG lasers were constructed in the form of an AlGaAs multiheterostructure, and their preliminary characteristics were obtained with both optical pumping and current injection at room temperature. The end mirrors of the active waveguide were fabricated by a back-sputtering method. The axial mode selectivity was predicted by the analysis and observed experimentally.
