研究了拉锥光纤中光透射率下降的原因。在制造后立即开始退化，并且最终将透射率降低到几乎为零。这是限制锥形光纤应用的一个主要问题。系统地研究了粉尘浓度和湿度对降解动力学的影响。结果清楚地表明，降解主要是由于灰尘颗粒，而与湿度无关。在无尘环境中，可以在1周内保持透射率的下降小于噪声（+/- 0.02）。(C)2011年美国光学学会
We investigated the cause of optical transmittance degradation in tapered fibers. Degradation commences immediately after fabrication and it eventually reduces the transmittance to almost zero. It is a major problem that limits applications of tapered fibers. We systematically investigated the effect of the dust-particle density and the humidity on the degradation dynamics. The results clearly show that the degradation is mostly due to dust particles and that it is not related to the humidity. In a dust free environment it is possible to preserve the transmittance with a degradation of less than the noise (+/- 0.02) over 1 week. (C) 2011 Optical Society of America
