Design and Study of Few-Mode Fibers at 1550 nm

الملخص

One of the most widely used technologies recently in the field of optical communications is the optical fiber technology. The aim of this paper is to design step-index few-mode fibers for use in optical communications and to study the effect of changing the core radius on the properties of their guided modes. Three core radii are compared: 9.5, 10.5 and 11.5 µm. The core refractive index is 1.45 and the cladding refractive index is 1.44. The properties of the guided modes were calculated at the wavelength 1550 nm using RP Fiber Calculator program. The results of this study showed that increasing the core radius leads to an increase in all the modes properties. Both amplitude and intensity modes profiles were illustrated.
