✦ Synopsis

A-type and V-type optical fibers are defined, according to the shape of the dielectric profile, and for each type, se¨eral structures are considered. Their modal characteristics are presented in graphical form, considering both small and ¨ery high ¨alues of the dielectric step. For the ( LP01 mode of weakly guiding structures small ¨alues of the dielectric ) ) step , the following is considered: 1 the ¨alue of the single-mode ( ) ) operation range LP11 cutoff , using a normalization criterion; 2 the frequency ¨ariation for both the classical dispersion data and the power ) confinement factor; and 3 the radial ¨alues for which the transmitted power falls both to one half of the total ¨alue and to one half of the core tra¨eling fraction, o¨er the limit of the single-mode operation range.

This paper presents models for inhomogeneous dielectric cylindrical structures, like optical fibers, with two different radial profiles: W-type and M-type. Graphs for modal characteristics are presented, considering both small and ¨ery high ¨alues of dielectric steps. Also, for the fundamental LP -m

## Abstract In this paper, we present a comparative study of different types of concave lens‐shaped dielectric waveguides and a dielectric square waveguide. Using the point‐matching technique under the weak‐guidance approximation, a general characteristic equation has been derived and modal dispers
