Highly sensitive temperature sensor using a Sagnac loop interferometer based on a side-hole photonic crystal fiber filled with metal.
A highly sensitive temperature sensor based on an all-fiber Sagnac loop interferometer combined with metal-filled side-hole photonic crystal fiber (PCF) is proposed and demonstrated. PCFs containing two side holes filled with metal offer a structure that can be modified to create a change in the birefringence of the fiber by the expansion of the filler metal. Bismuth and indium were used to exa...
متن کاملHighly Sensitive Fiber Michelson Interferometer Based on a Liquid-Filled Photonic Crystal Fiber with Dispersion Engineering
Photonic crystal fiber interferometers (PCFIs) with superiority of the unique fiber structure have been extensively developed as the all-fiber based strain () [1], external refractive index (RI) [2], chemical [3] and bending sensors [4]. The majority of the valuable applications on the fiber-optic sensing are all accredited to the air voids structured periodically in the photonic crystal fibe...
متن کاملFiber-optic Michelson interferometer with high sensitivity based on a liquid-filled photonic crystal fiber
This study proposes an ultracompact and highly sensitive liquid-filled photonic crystal fiber Michelson interferometer (LF-PCFMI) based on material dispersion engineering. Numerical simulations and experimental measurements are performed in the work, and both of their results show that the temperature sensitivity can be more greatly improved than those of conventional photonic crystal fiber int...
متن کاملPressure sensor realized with polarization-maintaining photonic crystal fiber-based Sagnac interferometer.
A novel intrinsic fiber optic pressure sensor realized with a polarization-maintaining photonic crystal fiber (PM-PCF) based Sagnac interferometer is proposed and demonstrated experimentally. A large wavelength-pressure coefficient of 3.42 nm/MPa was measured using a 58.4 cm long PM-PCF as the sensing element. Owing to the inherently low bending loss and thermal dependence of the PM-PCF, the pr...
متن کاملDesign and simulation of a highly sensitive photonic crystal temperature sensor based on a cavity filled with the distilled water
In this paper design and two dimensional (2D) simulation of a photonic crystal highly sensitive temperature sensor is presented. The 2D simulations are based on finite-difference time-domain (FDTD) method and are done using Rsoft software. The device is constructed using a cavity filled with the distilled water located in the center of the photonic crystal waveguide. The operation of the propos...
