摘　　要：Single frequency fiber lasers have attracted intense attention in the high precision measure,optical communication and Raman spectroscopy due to their special features including narrow spectral linewidth,low-intensity noise and fiber compatibility[1-5].Tunable fiber lasers with broad wavelength-sweeping range or fast wavelength-sweeping speed have become key components in dense wavelength division multiplexing(DWDM)transmission systems or high-resolution spectroscopy.具有良好单色性的可调谐光纤激光器是密集波分复用传输系统中的关键组件.传统的调制方法难与全光通信网络兼容.本文中,我们利用MXene(Ti2NTx)的强光热效应,对基于迈克尔逊干涉仪的全光波长调谐光纤激光器进行了研究.对于全光调制器来说,信号光的相移,随控制光功率具有0.03πm W-1的线性关系.获得25 d B的调制深度,有利于提高调制器的灵敏度以实现快速的波长扫描.另外,实现的全光波长调谐激光器具有大边模抑制比,宽波长调谐范围和窄3-dB光谱宽度.这种新颖的基于Ti2NTx的全光波长调谐器不仅扩展了全光调制器的应用领域,而且也为基于Ti2NTx的异质结构提供了可扩展的可用性,以构建高性能的全光纤激光器.
