掺铒光纤超荧光宽带光源的实验研究
The Experimental Research of a Broadband Erbium-oped Fiber Superfluorescence Source
摘要
全部采用国产元器件成功地研制出了掺Er3+光纤超荧光宽带光源,并对其功率特性、谱宽特性及其随温度的变化特性等作了初步实验分析,并取得了较为理想的实验结果。针对宽带光源自然荧光谱有尖峰结构造成频谱过窄的问题,提出了一种简单有效的改进方案,从而颇有成效地抑制了尖峰,扩展了频谱,得到了较为满意的频谱宽度。
Abstract
With all utensils made in China we have successfully manufactured a broadband Er 3+ doped fiber superfluorescence source. The basic characteristics of the superfluorescence source, such as the output power, output linewidth, and the change of the linewidth with temperature, have been analyzed and studied. And rather good experimental results have been obtained. To address directly the question why the natural fluorescence spectrum of the broadband source has a pinnacle structure which results in a too narrow linewidth, we present a simple but effective measure to restrain the pinnacle. Consequently, a spreaded frequency spectrum with a satisfactory width has been obtained.
