Abstract

A fairly rigorous analytical treatment of an annular core dielectric optical fiber is presented, the core of the fiber lying between two concentric claddings with the outer cladding extended infinitely. For the theoretical approach, the approximation of the vanishing refractive-index difference between the core and the cladding sections is implemented. The investigation is on the preliminary ground, and a numerical estimation of the modal cutoffs is presented for the said fiber. The effects of the core width as well as the inner core diameter on the propagation constants βc at field cutoffs are presented. Plots are also shown of the variation of βc with the change in the refractive-index values.
