摘　　要：本文采用1.3μm InGaAsP短自聚焦棒外腔半导体激光器作拍频及相干光传输实验。在多个波长点获得比较稳定的拍频信号;用拍频法测量了自聚焦棒外腔激光器单纵模线宽与注入电流的关系曲线。并进行了调制速率100MHz正弦信号相干FSK调制一解调实验。实验表明这类激光器可用于FSK调制的相干光纤通信系统。This paper reports the beat and coherent transmission experiments with 1.3 urn InGaAsP short graded index rod external cavity semiconductor laters. The stable beat patterns were obtained at several wavelength point The curve of the linewidth of graded index rod external cavity semiconductor laser vs the injection current was got by using beat method 100 MHz sinusoidal wave FSK modulation coherent transmission experiment was carried out. Experiments show that this kind of semiconductor laser can be used in coherent optical fiber communication systems
