1.55 μm波段集成外腔可调谐二极管激光器具有体积小、成本低、功耗低、调谐范围宽、线宽窄、边模抑制比大、输出功率高等优点。这些优点吸引了激光器的许多应用，例如波分复用、无源光网络、移动的回程和光谱传感技术。本文首先介绍了集成外腔可调谐二极管激光器的基本结构和原理，然后详细回顾和比较了1.55 μm波段外腔可调谐二极管激光器的两种主要集成结构，即1.55 μm波段集成外腔可调谐二极管激光器的混合集成结构和单片集成结构。最后，总结了近十年来1.55 μm波段集成外腔可调谐二极管激光器的研究进展，分析了1.55 μm波段集成外腔可调谐二极管激光器的优缺点。结果表明，随着光通信向更复杂的调制格式转变，集成小型化1.55 μm波段外腔可调谐二极管激光器是必要的。低成本集成的1.55 μm波段外腔可调谐二极管激光器有望应用于下一代光收发模块中的小因素模块。
The 1.55 μm waveband integrated external cavity tunable diode lasers have excellent merits such as their small volume, low cost, low power consumption, wide tuning range, narrow linewidth, large side mode suppression ratio, and high output power. These merits have attracted many applications for the lasers, such as in wavelength division multiplexing, passive optical networks, mobile backhaul, and spectral sensing technology. In this paper, firstly, the basic structure and principle of integrated external cavity tunable diode lasers are introduced, and then two main integrated structures of 1.55 μm waveband external cavity tunable diode lasers are reviewed and compared in detail, namely the hybrid integrated structure and monolithic integrated structure of 1.55 μm waveband integrated external cavity tunable diode lasers. Finally, the research progress in 1.55 μm waveband integrated external cavity tunable diode lasers in the last decade are summarised, and the advantages and disadvantages of 1.55 μm waveband integrated external cavity tunable diode lasers are analysed. The results show that, with the transformation of optical communication into more complex modulation formats, it is necessary to integrate miniature 1.55 μm waveband external cavity tunable diode lasers. Low-cost integrated 1.55 μm waveband external cavity tunable diode lasers are expected to be used in the next generation of optical transceivers in small-factor modules.
