Abstract

Coupled mode theory for power orthogonal modes is briefly reviewed. When the modes are not power orthogonal, modifications are necessary in the evaluation of the coupling coeffi cients and in the interpretation of power delivered to the output of a coupler, as pointed out by Hardy and Streiferl. In practical terms, these modifications lead to the presence of crosstalk in optical switches that may impair their operation. Two realizations of an optical switch are investigated and the amount of crosstalk as predicted by the "refined" coupled-mode theory is determined.
