Methods of analyzing planar optical waveguides.
We present a new approximate solution of the scalar-wave equation for planar optical waveguides with arbitrary refractive-index profiles. Test calculations are done for an index profile with a known solution. The comparison demonstrates the accuracy of our method. The method may also be applied to circularly symmetric optical fibers.
