A fast tunable dual-wavelength laser based on in-fiber acousto-optic Mach-Zehnder interferometer (AO-MZI) with new fabrication process is proposed. Not only could the center wavelength of the output laser be optimized with enhanced tuning range about 30 nm by tuning the polarization and the driving frequency of the radio frequency (RF) signal accordingly, but also the spectral spacing between the two output wavelengths could be tuned from ~0 nm to 2.65 nm by controlling the power of the RF signal. The tuning mechanism was also discussed.
提出了一种基于具有新型制造工艺的光纤声光马赫-曾德尔干涉仪（AO-MZI）的快速可调谐双波长激光器。通过相应地调整偏振和射频（RF）信号的驱动频率，不仅可以优化输出激光的中心波长，使调谐范围增强约30nm，而且通过控制RF信号的功率，可以将两个输出波长之间的光谱间距从~0nm调谐到2.65nm。还讨论了调谐机制。
