摘要：

A new local field analysis is proposed for bent planar waveguides with arbitrary refractive index profile. Exact vector wave equations that include the gradient index, or polarization correction, term are derived for both TE and TM modes from Maxwell's equations in a local bent coordinate system. The approximate local field and correction to the propagation constants are obtained by perturbation analysis. As an example of the method, an infinitely extended parabolic index profile is studied. © 1990 IEEE
