摘要：
In this paper, a photonic crystal fiber (PCF) pH sensor is demonstrated based on Transmission Mach-Zehnder interferometer (TMZI). Two sensors were fabricated. The general structure of sensor applied by fusion splices 2 cm and 4 cm of PCF between two multimode fibers (MMFs). The air holes in the adhesive regions completely collapsed to form a multi-media PCF interference. Because of the coupling between the core and the cladding modes the PCF-MZI were formed in the collapsed area. within the ranges of pH 4, 6, and 12, sensors were submerged in the solutions. The sensitivity of 2 cm sensor is equal 102 nm/pH TU and 125 nm/pH TU for 4 cm.
