摘要

研究了一种具有双包层结构的包层模谐振特种光纤,该特种光纤具有一个低折射率内包层,基于耦合模原理,纤芯模与包层模之间发生谐振耦合,从而获得具有带阻特性的传输光谱。系统介绍了包层模谐振光纤的制备、传输原理及其弯曲、溶液折射率、折射率/温度双参量等传感特性。实验和理论研究结果表明,包层模谐振特种光纤对于弯曲、溶液折射率参量具有良好的敏感性,此外,通过内包层掺杂可以调节包层模谐振光谱的温度敏感特性。

Abstract

A cladding mode resonant specialty optical fiber comprising a double cladding structure is proposed. The specific fiber has a thin and low refractive index inner cladding. Based on the coupled mode theory, a core mode can be resonantly coupled to a cladding mode, and then a band-reject spectrum can be obtained. We mainly introduce the fabrication technology, operation principle of the specific fiber and demonstrate its senor applications in bend, solution refractive index (RI) and RI/temperature dual parameters. As the theoretical and experimental results show, the specific fiber is sensitive to the parameters of bend and solution RI. Moreover, the temperature sensitivity of the specific fiber can be adjusted by different dopants in the inner cladding.
