“…Compared with energy-dependent sensor, the wavelengthdependent sensor gains the advantage of insensitive to the light source power, splicing loss, transmission loss and other environmental conditions. Recently, several configurations of optical fiber curvature sensor have been proposed, such as long period fiber grating (LPFG) [1]- [6], fiber Bragg grating (FBG) [7]- [9], tilted FBG [10], [11], Sagnac loop [12], [13], directional coupler [14] and MZI [15]- [20]. Usually, the fabrication of the former three types needs UV laser or CO 2 laser and accurately controlled devices to perform the lattices inside the fiber.…”

A simple and compact thin-core fiber (TCF)-based Mach-Zehnder interferometer (MZI) is proposed for curvature measurement. The sensor head is composed by a short section of TCF embedded between two single-mode fibers. The MZI works on the basis of interference between the core mode and cladding mode in TCF. The transmission spectrum of the sensor is analyzed by the fast Fourier transform, which indicates that the interference mainly occurs between LP 01 and LP 018 modes propagating in TCF. The experimental results show that the dip wavelengths in transmission spectrum decrease linearly as the curvature increase with a sensitivity of −13.53 nm/m −1 . The high curvature sensitivity makes this sensor a candidate for curvature discrimination and measurement in the field of structural deformation, intelligent artificial limb, and mechanical engineering.Index Terms-Bending measurement, curvature sensor, Mach-Zehnder interferometer, thin-core fiber.

, respectively. This simple MZI is formed by invoking interference between LP 01 and LP 21 core modes, which leads to that the sensor is not sensitive to ambient refractive index (ARI). The temperature sensitivity has also been investigated. Two dips have obviously different sensitivities on the temperature and bending, so two parameters of both curvature and temperature can be distinguished and measured simultaneously by constructing a matrix and using one simple model interferometer.

“…The core mode diameter gets increased due to tapering and part of it can be easily coupled to the cladding mode(s).This method is relatively very simple and cost effective but mechanically weak especially at the tapering region. Besides these, MZIs are formed using double cladding fiber [10], micro-cavities [11], and a twin-core fiber [12] …”

This paper describes the design of Mach Zehnder Interferometer and reviews its applications in emerging optical communication networks. Mach Zehnder Interferometer is basically used to measure relative phase shift between two collimated beams from a coherent light source. Using this basic principle a number of devices can be designed, few of these such as optical sensors, all-optical switches, optical add-drop multiplexer and modulator are discussed in this paper.
