Abstract:

The surface-wave propagation on a curved optical waveguide of arbitrary cross-section is calculated. A formulation is employed which retains much of the simple physical interpretation of the slab case. Specific attention is given to the case where the guided mode does not possess any symmetry with respect to the bending axis. In this case the change in propagation constant for such a situation can cause not only a significant additional phase shift around the bend, but also quite sizeable enhancement or reduction in the amount of continuous radiation loss. For the circular symmetry cross-section the results agree except for a factor of 12 with previous calculations obtained by an integral representation of fields.
