摘要
报道了一种基于掺铒光纤的两级宽带光源.通过采用双通结构和循环利用C波段放大自发辐射,极大地节省了用于产生L波段放大自发辐射所需的泵光功率.利用一支啁啾布拉格光栅作为光谱平坦器,实现了76 nm的平坦输出光谱.
A two-stage broadband erbium-doped fiber based amplified spontaneous emission （ASE） source is presented. By using double pass configuration and recycling backward C band ASE, the pump power for L-band ASE generation is much economized. With a chirped fiber Bragg grating （CFBG） as spectrum equalizer, a flat spectral bandwidth of 76 nm is realized.
