Abstract

A fiber-optic Fabry-Perot interferometer was constructed by splicing a short length of photonic crystal fiber to a standard single-mode fiber. The photonic crystal fiber functions as a Fabry-Perot cavity and serves as a direct sensing probe without any additional components. Its pressure and temperature responses in the range of 0-40 MPa and 25 °C-700 °C were experimentally studied. The proposed sensor is easy to fabricate, potentially lowcost, and compact in size, which makes it very attractive for high-pressure and high-temperature sensing applications.
