| 摘 要： | 基于多模光纤(MMF)引入的偏振烧孔(PHB)效应,研制了一种环形双波长掺铒光纤(EDF)激光器.单模光纤(SMF)-MMF-SMF组成的结构使MMF不同偏振方向的反射模在波长上分开,利用PHB效应实现双波长的输出,输出波长间隔可通过改变MMF的长度改变.实验对比了1.6 m和3.0 m长的MMF输出波谱特性,结果表明...

| Abstract: | A dual-wavelength Er-doped fiber laser based on polarization hole burning(PHB) of multi-mode fiber is proposed.The structure of single mode fiber(SMF)-multi-mode fiber(MMF)-SMF makes reflection modes in different polarization directions of MMF split.Thus,dual-wavelength laser output is realized through PHB.Moreover,the wavelength spacing can alter through changing the length of MMF.In this paper,the output characteristics are compared when a MMF with length of 1.6 m and 3 m are introduced,respec... |
