Abstract

A temperature self-compensating extrinsic Fabry-Perot cavity and a manufacturing method solve the problem that the existing extrinsic Fabry-Perot cavity is affected by temperature, and belong to the technical field of optical fiber sensing. The extrinsic Fabry-Perot cavity of the present invention comprises a sapphire diaphragm, a silicon dioxide base and a sapphire column, the sapphire diaphragm is located at the top of the silicon dioxide base, and the silicon oxide base is formed by a silicon dioxide sidewall It is composed of a silicon dioxide base; the silicon dioxide side wall, the silicon dioxide base and the sapphire diaphragm form a vacuum chamber, and the sapphire column is arranged in the vacuum chamber and fixed at the bottom center of the sapphire diaphragm. The invention also provides a manufacturing method. The invention enhances the application temperature range of the extrinsic F-P cavity, reduces the cost, and allows light to transmit in the F-P cavity without large transmission loss, increases the service life of the F-P cavity, and adapts to a wider range The temperature compensation of the optical signal is carried out within the temperature range, which greatly reduces the workload of the optical demodulation part.

Description

Technical field [0001] The present invention provides a temperature self-compensating non-intricular method of Bribertulaum and manufacturing methods, belonging to the field of fiber sensing technology. Background technique [0002] Due to the small size of the Fabry-Perot, FP), the sensitivity is high in measurement temperature, pressure, vibration, and acoustic wave, etc., the anti-electromagnetic interference performance is good, so it has been in engineering applications in engineering applications. Very large use value. However, the unusual F-P fiber sensor is measured when measuring the physical quantity other than the temperature, and the error signals caused by calibrating the ambient temperature. [0003] Conventional production of non-intrinsic F-P chambles is inserted into a capillary having a single-mode fiber having good verticality into a capillary that matches the fiber diameter to ensure the end surface of F-P and vertical. However, this F-P chamber is about 3.676...
