Abstract

The principal purpose of this paper is to compare calculated and measured impulse responses of multimode optical fibers to substantiate the validity of the theoretical approach now being used by investigators. To perform the comparison efficiently, a new, practical method of analysis of the impulse response of inhomogeneous optical fibers is presented first. The necessary input data for calculating the impulse response are refractive indices at N points, refractive index in the cladding, core radius, and the wavelength of the light source. The calculated impulse responses are compared with the measured ones for several multimode optical fibers, showing good agreement.
