Abstract

We describe an in-fiber interferometer based on a gas-filled hollow-core photonic crystal fiber. Expressions for the sensitivity, figure of merit and refractive index resolution are derived, and values are experimentally measured and theoretically validated using mode field calculations. The refractive indices of nine monoatomic and molecular gases are measured with a resolution of δn < 10.

摘要

我们描述了一种基于充气空心光子晶体光纤的光纤干涉仪。推导了灵敏度、品质因数和折射率分辨率的表达式，并通过实验测量了这些值，并使用模式场计算进行了理论验证。测量了九种单原子和分子气体的折射率，分辨率为δn < 10。
