Bending optical waveguide investigation for electromagnetic field radiation and propagation application

Abstract

This paper presents the analysis of bending optical waveguide based on effective refractive index and beta propagation constant. The various sample of core waveguide size such as 3 ×3, 7×7 and 9×9 is taken and measure with radius curvature of optical waveguide. The data collection based on Maxwell equation derivation and modeling electromagnetic field as a engine behind of graphical user interface (GUI) simulation. The material that 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 and result of optimization analysis of waveguide according to a certain parameter may help in Telecommunication application design and modeling such as optical fiber, wave propagation, and electromagnetic field radiation for angular field.
