Abstract
In the present paper, a ring-core four-clad optical fiber of silica glass has been proposed. The fiber has been designed in such a way that a certain difference in refractive indices between consecutive layers can exist. The impact of changes in effective refractive index and difference in refractive index on the dispersion of the propagating signal, and phase constant is also investigated using the COMSOL 5.3a and Matlab 2018b software. It is discovered that this kind of structure provides a very less amount of multimodal loss.
