Abstract: We present the use of the Douglas-Gunn Alternating Direction Implicit finite difference method for computationally efficient simulation of the electric field propagation through a wide variety of optical fiber geometries. The method can accommodate refractive index profiles of arbitrary. Optical Fiber Simulation in MATLAB thesis ideas along with simulation guidance are supported by us in a very novel way for scholars if you are looking for customized services you can approach us by sharing all your project details to us. The process of simulating an optical fiber system is examined. Each optical fiber represents a transmission system, which is a frequency dependent. From the equation we can obtain effects in optical. Building on the scientific understanding and technological infrastructure of single-mode fibers, multimode fibers are being explored as a means of adding new degrees of freedom to optical technologies such as telecommunications, fiber lasers, imaging, and measurement. Here, starting from a baseline.
