Microwave approach to a class of highly irregular fiber optics

Abstract

Variably coupled-mode theory developed decades ago in the microwave art is rediscovered to be a powerful mathematical tool in dealing with highly irregular fiber optics, whose analytic solution would have been extremely difficult to obtain if adopting a regular optical method. Examples treated in this presentation are the author's new invention of a set of fiber-optic analogues of bulk-optic wave plates. Experimental data exactly confirm theoretical predictions.
