A New Approach to Modal Index Determination for Planar Waveguides
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.
