摘要：
We discuss a method of evaluating the effective indices of quasi-modes of a bent rectangular core waveguide taking into account the correct dielectric constant of the corner regions, which is ignored in earlier methods. At small bend curvatures and low V values, the corner regions contribute much more to the effective index change than the bending itself. (C) 1994 John Wiley & Sons, Inc.
