Fiber Optic sensor technology has become more popular since early 1970’s during which the mechanism of losses from optical fibers was exploited to construct a new class of fiber optic sensors and systems. A novel fiber optic sensor has been developed by connecting a U-shaped glass element of specific dimensions between a light source of 660nm wavelength and an optical power detector by using a couple of PCS optical fibers of 200/230μm diameters of core and cladding respectively. The sensor can be employed to measure several parameters such as Refractive Index, Density, Viscosity, Ultrasonic Velocity, Molar Volume, Molar Refraction, Dielectric Constant, Acoustic Impendence, Adiabatic Compressibility, Viscous Relaxation Time, Intermolecular Free Length, Absorption Coefficient, Gibb’s Free Energy, Free Volume, Internal Pressure and their excess parameters of Toluene and tert-Butanol mixtures at 30℃ temperature and at the operating wavelength of 660nm

Operating Wavelength

A cost effective and simple fabrication process for Mach Zehnder Interferometer (MZI) fiber based sensor has been proposed based on single mode-multimode-single mode structure and multimode-single mode-multimode. These proposed structures employed a standard fusion arc splicing by varying the length of sensing region instead of the structures. This sensor has been experimentally demonstrated for three different concentration of solutions such as water, 1mol sucrose solution and oil with the refractive index of 1.333, 1.384 and 1.464 respectively. Furthermore, the intention of this experiment is to determine which structure that provides superior performance in terms of the sensitivity of the device. The operating wavelength of different structures corresponds to the different refractive index. It is observed that the shifting response was influenced by the length of the sensing-area and the best sensitivity achieved for is -10.45nm/RIU.
