| Abstract: | A new approach to modal index determination for planar waveguides is presented, which is an extension of the Ruschin-Lit mode counting rule. Unified half phase shift relations related to the above rule are improved and completed. The approach applied to some special waveguides and numerical results are given. |

| Keywords: | planar waveguides modal index |
