基于粉末烧结技术制备镱铝共掺大模场光子晶体光纤

采用粉末烧结技术制备出高浓度镱铝共掺石英棒，Yb3+掺杂浓度为12 000 ppm(wt).利用此掺镱石英棒作为纤芯,拉制出镱铝共掺大模场光子晶体光纤，光纤模场面积为550 μm2，模场直径26 μm.实验结果表明：光纤在近红外波段(850~1 033 nm)出现一个宽的吸收带,主吸收峰波长位于976 nm，在此波长处吸收损耗高于10 dB/m；采用波长为971 nm的激光泵浦光纤，在1 050~1 125 nm波长范围内产生高斯型的荧光峰，峰值波长位于1 088 nm处，荧光半宽高45 nm.

Abstract

Based on powder sintering technology, Yb3+/Al3+ codoped silica rods are prepared, and the concentration of Yb3+ is up to 12 000 ppm (wt). Then, with the Yb3+/Al3+ codoped silica rods as core materials, highly doped Largemodearea Photonic Crystal Fibers (LMAPCF) are fabricated by stackdraw method. The mode area can reach 550 μm2, and the mode field diameter is 26 μm. The results indicate that the fiber has a broad absorption band in the near infrared wavelength (850~1 033 nm), and the main peak is at the wavelength of 976 nm where the absorption loss is higher than 10 dB/m; when the fiber is pumped by the laser with a wavelength of 971 nm, there exists a Gaussian fluorescence peak in the wavelength range of 1 150~1 125 nm, with a peak value of 1 088 nm and a halfline width of 45 nm.
