We in¨estigate the numerical instability of a finitedifference beam-propagation formulation applied to tapered optical wa¨eguides, and we find that instability may occur with the use of con¨entional transparent boundary conditions. We suggest modified transparent boundary conditions to remo¨e the in

In this article we use the implicit finite-difference beam propagation method (implicit FD-BPM) to calculate acceptor density profiles created by the diffusion of Zn into InP, InGaAs, and InGaAsP. We verify the accuracy of this method by comparing our computed results with carrier density profiles m
The paper deals with the boundary value problem for a nonlinear integro-differential equation modeling the dynamic state of the Timoshenko beam. To approximate the solution with respect to a spatial variable, the Galerkin method is used, the error of which is estimated.
