dc.description.abstractFiber Bragg grating (FBG) sensors can encode an interest of measurements, such as strain and temperature, into an optical wavelength. A comparative advantage of FBG sensors is their ability to be interrogated in a distributed way using multiplexing techniques. The wavelength-division multiplexing (WDM) is a fiber-optic communication technology which uses different wavelengths of light to multiplex different optical carrier signals onto a single optical fiber. This technique makes bidirectional communications over a single fiber possible, as well as increases capacity. Thus, in this project, the working principle of the wavelength division de-multiplexer is investigated. Firstly, the behavior of ideal and non-ideal Mach-Zehnder interferometer is analyzed. Both ideal and non-ideal wavelength division de-multiplexers are designed and simulated. The second stage of the project involves a design of actual wavelength-independent directional coupler for a wavelength range of interest of 1260nm to 1340nm. The behavior of the wavelength- independent directional coupler is simulated using COMSOL and MATLAB.en_US
