摘　　要：针对相干光通信系统对窄线宽可调谐激光器的要求,提出并实际研制了一种基于MEMS(微电子机械系统)技术的外腔可调谐激光器,分析了外腔参数对激光器性能的影响。该激光器尺寸符合光互联论坛关于ITLA(集成可调谐激光器组件)的标准01.2,调谐范围覆盖C波段内40nm,输出功率N13dBm,光谱线宽N100kHz。为进一步验证器件的性能,使用该激光器作为本振光源,验证了它在基于PM-DQPSK(偏振复用-四相相移键控)的100Gbit/s传输系统中的性能,实验结果表明,该激光器可作为高速相干光通信系统中窄线宽可调谐光源的理想选择。In view of the requirements of coherent optical communication systems for narrow linewidth tunable lasers, this pa-per presents and develops an external cavity tunable laser using the MEMS technology and analyzes the influence of component parameters in the external cavity on the laser performance. The packaged device has a compact dimension conforming to OIF-MSA-ITLA-01.2, a tuning range of 40 nm in the C-band, a narrow linewidth of less than 100 kHz and output power of larger than 13 dBm. It tests this device in a 100 Gbit/s PM-QPSK system using the developed laser as the intrinsic source and the re-sults show that this laser is ideal candidate for narrow-linewidth tunable source in high-rate coherent optical communication sys-terns.
