摘要：

We demonstrate a novel polyvinyl chloride (PVC) diaphragm-based fiber-tip Fabry-Perot interferometer for gas-pressure measurements with ultrahigh sensitivity. The PVC diaphragm has been coated to the end facet of a well-cut standard single-mode fiber by use of a plastic welder. An ultrahigh-pressure sensitivity of similar to 65.5 nm/MPa at 1565 nm and a low-temperature cross sensitivity of similar to-5.5 kPa/degrees C have been experimentally demonstrated. The proposed sensor has advantages of high pressure sensitivity, miniature size, low cost, and easy fabrication.
