Description

<jats:p>The phenomenon of electromagnetically induced transparency (EIT) is demonstrated in a surface plasmon polariton waveguide at infrared frequencies. The comb line slot and rectangle cavity are placed inside one of the metallic claddings, and their coupling intensities among them are utilized to obtain bright and dark states. The destructive interference between the bright and dark states leads to an EIT-like transmission spectrum of the waveguide. The induced transparency peak can be manipulated by adjusting the coupling distance between the bright and dark states. Finally, the influence of Joule loss on the EIT-like effect is investigated. It is found that the EIT-like transmission contrast is sensitive to the variation in the metallic damping factor.</jats:p>
