Abstract

A microminiaturized all-fiber Fabry-Perot interferometer (FPI) for high-temperature sensing has been proposed and experimentally demonstrated. The FPI is composed of a micro-air bubble and a taper probe with a tip less than 2 μm in diameter as reflected interfaces. A temperature sensitivity of 14.68 pm/°C near the wavelength of 1550 nm is obtained. The sensor, with its miniature size, can work in an ultra-small space with a large range of temperature variation.

摘要

一种用于高温传感的微型全光纤法布里-珀罗干涉仪（FPI）已被提出并通过实验验证。该FPI由一个微气泡和一个直径小于2μm的锥形探头作为反射界面组成。在1550nm波长附近获得了14.68pm/°C的温度灵敏度。该传感器尺寸微小，可在温度变化范围大的超小空间内工作。
