A multiwavelength semiconductor optical amplifier (SOA) fiber laser based on all‐fiber two‐mode interferometer (TMI) structure is demonstrated. The TMI generates in a comb‐like spectrum with a 1‐nm wavelength spacing and extinction ratio of 5.7 dB. By incorporating a TMI in the laser cavity, stable multiwavelength operation is obtained with 30 output channels from 1570.8 to 1600.8 nm with peak powers of at least 10 dB from the highest peak. The output comb spectrum and the overall stability of the multiwavelength are also enhanced with by inducing the four‐wave‐mixing effect in the cavity. The multiwavelength SOA fiber laser shows high operational stability with peak power fluctuations exceeding 1 dB observed only at the 1^st, 23^rd, 26^th, and 30^th peaks, which are at the ends of the multiwavelength spectrum.

使用2模干涉仪的稳定多波长半导体光放大器光纤激光器

演示了基于全光纤双模干涉仪（TMI）结构的多波长半导体光放大器（SOA）光纤激光器。TMI产生梳状频谱，其波长间隔为1 nm，消光比为5.7 dB。通过将TMI集成到激光腔中，可以获得30个输出通道（从1570.8到1600.8 nm）的稳定多波长操作，且其最高峰值功率至少为10 dB。通过在腔中引入四波混频效应，还可以提高输出梳状谱和多波长的整体稳定性。与峰值功率的波动超过1 dB的多波长光纤SOA激光表演高操作稳定性仅在1观察到的^第一，23^次，26^次和30^次 峰值，位于多波长光谱的末端。
