We propose and demonstrate a simple dual port tunable from the C- to the L-band multi-wavelength fiber laser based on a SOA designed for C-band operation and fiber loop mirrors. The laser incorporates a polarization maintaining fiber in one of the fiber loop mirrors and delivers multi-wavelength operation at 9 laser lines with a wavelength separation of ~2.8 nm at room temperature. We show that the number of lasing wavelengths increases with the increase of the bias current of the SOA. Wavelength tunability from the C to L-band is achieved by exploiting the gain compression of a SOA. Stable multi-wavelength operation is achieved at room temperature without temperature compensation techniques, with measured power and the wavelength stability within < ±0.5 dB and ±0.1 nm, respectively.
我们提出并展示了一种简单的双端口可调谐多波长光纤激光器，其波长范围从C波段到L波段，该激光器基于一个专为C波段运行设计的半导体光放大器（SOA）和光纤环形镜。该激光器在其中一个光纤环形镜中采用了保偏光纤，在室温下以9条激光线实现了多波长运行，波长间隔约为2.8 nm。我们表明，激射波长的数量随着SOA偏置电流的增加而增加。通过利用SOA的增益压缩实现了从C波段到L波段的波长可调谐性。在室温下无需温度补偿技术即可实现稳定的多波长运行，测量得到的功率和波长稳定性分别在<±0.5 dB和±0.1 nm范围内。
