摘要：
A scalar variational approximation is proposed to calculate the propagation constant and the normalised dispersion parameter of LP11 mode of double clad fibers. Single and two parameter variational approximations have been proposed in this work. Also, a numerical method has been developed for the computation of these parameters. It has been demonstrated that the two parameter variational approximation calculates the propagation parameters more accurately than single parameter variational approximation over a wide range of fiber parameters. These values of the parameters, computed using variational approximations, have been verified with the exact results obtained numerically.
