Bending Waveguide Modeling for Light Trapping Into Optical Fiber

摘要

This paper presents the simulation of Bending Waveguide on propagation characteristics on light intensity distribution. The material that will be used is GaAs for core refractive index, while material GaAlAs for upper and lower refractive index. The structure for this Bending Waveguide is set at 1.55 μm. The effective refractive index, n_(eff) and normalized propagation constant, b has been considered on this simulation. The engine behind this simulation is Finite Difference Method (FDM). MATLAB programming has been used as the method of simulation. The result of optimization analysis of waveguide according to a certain parameter may help in application of designed modeling performance of Bending Waveguide easily.
