Tunable laser module based on REC technology

通过重构-等效啁啾（REC）技术实现了一种基于分布式反馈（DFB）激光器矩阵的低成本可调谐激光器模块,对该模块进行了波长调谐、稳定性以及其他性能的测试,并将特定波长的参数加以标定。模块中的相邻激光器之间的中心波长间隔均匀等距且P-I特性良好,可调谐激光器输出波长的波动小于±3 pm,光功率变化小于0.02 d Bm。波长调谐范围为1536.64～1559.36 nm,在该范围内依照ITU-T的DWDM标准涵盖了60特定波长通道,通道切换时间为5～30 s。

A low cost tunable laser module based on distributed-feedback（ DFB） laser matrix is achieved by reconstruction-equivalent-chirp（ REC） technology. Wavelength tuning,stability and other performance tests are applied,and the parameters of specific wavelength are calibrated. The wavelength spacing between adjacent lasers in the module is uniform,and the P-I diagrams are good. The output light of this tunable laser has a wavelength fluctuation within ± 3 pm and a power fluctuation less than 0. 02 d Bm. The wavelength-tuning range is 1536. 64 ～ 1559. 36 nm,which can covers 60 specific wavelength channels according to ITU-T DWDM standard,and the channel-switching time is 5 ～ 30 s.
