利用C波段ASE补偿的双通掺铒光纤宽带光源(英文)
A Double-pass Erbium-doped Fiber Based Broadband ASESource by Utilizing C-band ASE Compensation
【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.
【Abstract】 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.
