✦ Synopsis

We obtain the characteristic equations and modal dispersion cur¨es of optical fibers with different degrees of metal loading on the core᎐cladding boundary. If p is the fraction of the circular boundary which is metal loaded, we consider four cases, so that p takes the ¨alues 1r4, 1r2, 2r3, and 3r4 successi¨ely. A comparison of the dispersion cur¨es shows that, as p increases, the number of modes sustained also ( ) increases, the other parameters like the operating wa¨elength , the core ( ) () and cladding refracti¨e indexes n and n , and the core radius a 1 2 being kept constant.
