title: Simple numerical technique for the analysis of cylindrically symmetric refractive-index profile optical fibers.
abstract: We extend an earlier proposed matrix method for the analysis of cylindrically symmetric arbitrary refractive-index profile optical fibers to calculate the propagation constant and leakage/absorption loss of modes. This method involves only straightforward multiplications of 2 x 2 matrices and is highly attractive, since no complex plane iterations are performed even to obtain leakage or absorption losses. Thus the method is ideally suited for implementation on desktop computers. The applicability of the method has been shown through calculations of propagation constants and leakage loss of the LP(01) mode in depressed inner clad fibers.
