Ray tracing solution of inverted graded index fibers

Abstract

Although extensive work has been done over the last 40 years on propagation in multimode fibers, and especially on graded-index fibers, research in this field is still very active. Recently, new fibers with an inverted refractive index profile (from now on IGI fibers), which increases as one moves away from the fiber axis, have been developed. These fibers have been shown to be effective for the design and development of chemical and biological optical fiber sensors. However, to date no general solution for ray propagation in these fibers has been found. In this paper we will show the general solution for ray propagation in IGI fibers. We will also show other relevant results such as the classification of the rays, the solution for particular cases of meridional and skew rays, the position of the internal caustics and the ray half period among others.
