Abstract

A hydrostatic pressure sensor based on a custom made two-core photonic crystal fiber (TC-PCF) is experimentally demonstrated. The TC-PCF was fabricated in our lab using standard PCF fabrication techniques. A hydrostatic pressure sensor based on the in-line fiber Mach-Zehnder interference is reported. The two solid cores of the TC-PCF separated by an air hole acted as the two arms in the interferometer. The pressure sensor has high repeatability and high sensitivity of -54.06 pm/MPa.
