摘　　要：利用单角度面半导体增益芯片及光纤布拉格光栅,研制了1310 nm波段的窄线宽混合集成外腔半导体激光器(ECDL)。该ECDL集成在一个紧凑的蝶形封装结构中,当工作温度和电流设置为25℃和280 mA时,EDCL的发射波长为1309.8 nm, 3 dB洛伦兹线宽为18 kHz, 3 h功率漂移量为0.6 mW,频率漂移量为315 MHz。另外,在工作温度为25℃时,激光无跳模电流调谐范围为7 GHz,调谐系数为47 MHz·mA^(-1)。该ECDL可广泛应用于光纤传感和光纤通信等领域。Objective With the development of modern communication network technology, people’s demand for communication capacity has increased dramatically, making the ultra-large capacity and long-distance optical fiber network transmission system a research hotspot in the field of optical fiber communication. As a light source with a comb-shaped spectrum in the frequency domain, the optical frequency comb can significantly increase the transmission capacity of a single optical fiber, make full use of the limited available bandwidth of optical fiber transmission, and become an ideal light source for large-capacity transmission in optical fiber network transmission systems. To improve the stability of large-capacity optical fiber communication system, it is necessary to examine the changes of the optical fiber link in the optical fiber communication system. However, the frequency coverage of the optical frequency comb is relatively wide, about dozens or even hundreds of nm, and the wavelengths needed for monitoring should avoid the band that carries information. Therefore, for a 1550 nm band optical frequency comb conventionally deployed in the current optical fiber communication system, a 1550 nm band laser cannot realize the monitoring of the optical fiber link in the optical fiber communication system. As another essential window of optical fiber communication, a 1310 nm band can realize the transmission with low attenuation and dispersion and has become an essential channel for optical fiber link detection. Therefore, it is necessary to study 1310 nm band narrow linewidth laser to improve the stability of the optical fiber communication system.Methods In this study,we have developed a 1310 nm band hybrid integrated external cavity diode laser based on the single angle facet semiconductor gain chip and fiber Bragg grating.First,the design and fabrication theory of the external cavity diode laser is presented.The fiber Bragg grating and ceramic substrate with V-groove are packaged by full-glue packaging process,which im
