Description

<jats:title>Abstract</jats:title><jats:p>We introduce a novel two-oscillator model with damping factor to describe the plasmon induced transparency (PIT) in a bright-dark model plasmonic waveguide system. The damping factor γ in the model can be calculated from metal conductor damping factor γ<jats:sub> <jats:italic>c</jats:italic> </jats:sub> and dielectric damping factor γ<jats:sub> <jats:italic>d</jats:italic> </jats:sub>. We investigate the influence of geometry parameters and damping factor γ on transmission spectra as well as slow-light effects in the plasmonic waveguide system. We can find an obvious PIT phenomenon and realize a considerable slow-light effect in the double-cavities system. This work may provide guidance for optical switching and plasmon-based information processing.</jats:p>
