Herein, we propose and experimentally demonstrate a novel, to the best of our knowledge, all-fiber Fabry–Perot (FP) interferometer that is formed by a simple angled fiber that can function as a beam splitter. According to the principle of the angled fiber, we verify the influence of an oblique angle on the light propagation path and light intensity ratio. Subsequently, angled fiber-based FP interferometers are experimentally demonstrated, and the influence of the oblique angle on the visibility of interference fringes and temperature characteristics is investigated. Finally, the temperature characteristics of this proposed FP interferometer are investigated experimentally, and the temperature sensitivity is 12.62 and 10.89 pm/°C for 42° and 40° angled fiber-based fiber FP interferometers, respectively. This proposed FP interferometer is fabricated by using a simple angled fiber, which has the advantages of ease of fabrication and all-fiber characteristics and hence can meet the requirements of mass production and high stability in various practical application areas.
