摘要
提出了一种用He-Ne激光侧面照射光纤光栅、从另一侧探测光栅的布拉格衍射效率来测量光纤光栅光谱特性的技术,并用该技术测量了光栅的折射率变化的分布。
Abstract
A new technology for measuring the characteristics of fiber gratings is described. By projecting a beam from a HeNe laser onto the fiber grating transversely and measuring the first Bragg diffraction, the property of fiber gratings can be measured. Based on this technique, the distribution of reflective index of the fiber grating can be obtained.
