Abstract

In this paper, the impact of fluctuations of graded-index (GRIN) optical fiber parameters on propagation of Gaussian beams is investigated by using ABCD matrix approach and a stochastic process. Since GRIN optical fibers have many applications in the optical communications, variations of fiber parameters such as core refractive index, core-cladding index difference and core radius affect the propagation of optical signals. Results show that the variations of the mentioned parameters change the beam spot size as well as the periodicity of the beam. Also, the fluctuations of such fiber parameters increase the spot size of the output Gaussian beam in comparison with the case when the fluctuations are ignored.
