提出了一种l波段双波长掺铒光纤激光器的光双稳性映射和波长切换新技术。通过在基于3db光纤耦合器的光纤环镜中插入偏振控制器（PC），可以调节光纤环镜的反射率。当FLM作为激光器的共反射面时，可以控制激光器的双稳性随FLM反射率的单调变化。基于这一特性，可以通过调整任意泵浦的PC，在最大FLM反射率的双稳性第一个拐点和最小FLM反射率的双稳性第二个拐点之间，分别对激光的双稳性和双波长进行映射和切换
A novel technique to map the optical bistability and to switch the wavelengths of an L-band dual-wavelength erbium-doped fiber laser is present. By inserting a polarization controller (PC) into a fiber loop mirror (FLM) based on a 3-dB fiber coupler, the FLM reflectivity can be adjusted with the PC. When the FLM is used as the common reflector of the laser, the bistability of the laser can be controlled to vary monotonically with the FLM reflectivity. Based on this property, the bistability and the dual-wavelength of the laser may be respectively mapped and switched with respect to each other by adjusting the PC for any pump when it is between the first turning point of the bistability for maximum FLM reflectivity and the second turning point of the bistability for minimum FLM reflectivity
