提出了一种基于紧凑型光纤马赫-曾德尔干涉梳状滤波器的室温可开关多波长掺铒光纤环形腔激光器。梳状滤波器是由一段双芯光纤拼接在两个单模光纤之间形成的。通过适当调节偏振控制器的状态，可以使激光器工作在稳定的单波长、双波长和三波长激射状态。其工作原理是基于饱和效应引起的光谱烧孔和偏振烧孔。
A switchable multi-wavelength erbium-doped fiber ring laser based on a compact in-fiber Mach–Zehnder interferometer comb filter at room temperature is presented. The comb filter is formed by splicing a section of twin-core fiber between two single mode fibers. By adjusting the states of the polarization controller appropriately, the laser can be made to operate in stable single-, dual- and three-wavelength lasing states. The operation principle is based on spectral hole burning induced by the saturated effect and polarization hole burning.
