摘　　要：介绍了可调谐激光器的波长调谐范围从1310 nm到1319 nm的波长控制设计,并对其可行性进行了实验测试验证。此系统采用的激光芯片是基于重构-等效啁啾(REC)技术的分布反馈(DFB)激光阵列芯片,具体通过上位机(PC)和下位机(MCU)之间的通信实现激光器阵列波长调谐。研究结果表明,该系统可应用于1310 nm波段的密集波分复用(DWDM)系统并且能够保持50 GHz间隔0.01 nm的波长精度。Design of wavelength control of a tunable laser with the wavelength tunable range from 1310 nm to 1319 nm is introduced and its feasibility is verified by experimental tests. The laser chip adopted by this system is distributed feedback （DFB） laser array based on reconstruction-equivalent-chirp （REC） technology and the realization of wavelength tunning is based on the interaction between the upper computer [personal computer, （PC）] and lower computer [micro controller unit, （MCU）]. The results demonstrate that this system applied to dense wavelength division multiplexing （DWDM） in 50 GHz spacing at 1310 nm can keep the wavelength accuracy within the range of 0.01 nm.
