Abstract
We investigate the numerical instability of a finite-difference beam-propag
ation formulation applied to tapered optical waveguides, and we find that i
nstability may occur with the use of conventional transparent boundary cond
itions. We suggest modified transparent boundary conditions to remove the i
nstability by controlling the amount of outgoing energy flux from waveguide
structures. (C) 1999 John Wiley & Sons, Inc.
