Abstract

We report on the problem of light propagation in tunnel-coupled waveguides. The theory of switching and forming of localized and delocalized waves in the annular system of coupled waveguides was developed. We first studied the localization of waves in nonlinear defective waveguide. It was shown that the degree of localization increases with increasing nonlinearity coefficient or intensity of input emission in defective waveguide. An effect of defective waveguide screening from neighboring zero-defect waveguides was found. Conditions for excitation of the rotatory switching in coupled waveguides with linear defect were found.
