Abstract

This paper theoretically analyzes the optical transmission characteristics of an optical waveguide when coupling to a micro cavity array. The results showed that not only were there sharp peaks on the transmission and reflection spectra, but also that a certain system configuration can produce a backward wave to obtain a phase shift in the small detuning range between the incident wave and the micro cavities. Based on a discussion of the relationship between the transmission and the number and the dissipation coefficients of each coupled micro cavity, the paper proposes a high efficiency all-optical switch model.
