摘要: 采用MCVD结合溶液掺杂技术制备了铒铋共掺的SiO2-Al2O3-GeO2光纤预制棒，测试其吸收和发射光谱，观测到铒铋宽带共同发光现象，该结果对于开发新型宽带放大光纤材料有指导意义，所得到的预制棒可望用于1.3 um窗口和S波段新型光纤放大器的研究。 The modified chemical vapor deposition (MCVD) combing solution doping method is applied to the fabrication of erbium and bismuth-doped Silica preforms. Erbium and bismuth co-doped SiO2-Al2O3-GeO2 preforms with near-infrared broadband luminous are realized. The characteristic spectra of preforms are experimentally investigated, and the common luminous phenomenon of erbium and bismuth is observed. The experimental results are of instructive significance for developing new optical fiber materials of wideband amplification and the prepared erbium and bismuth-doped optical fiber preforms are expected to be used for the study on the new amplifier with 1.3 um window and S wave band.
