Abstract

The mode-matching method is used to analyse the dispersion characteristics of single and asymmetrical double groove guides, and the unified formulae of Nth-order approximation dispersion equations are presented. A general program for calculating the dispersion characteristics of the groove guides has been completed. Some comparisons between the results obtained by present method and those in the literature are made, and very good agreement has been seen. The effectiveness and the reliability of the formulae and the program are thus justified. The theoretical coupling characteristics of an asymmetrical double groove guide coupler are given to demonstrate how flat coupling can be obtained with this coupler.
