Active Control of Slow Light in a Gain-Assisted Plasmon-Induced Transparency Structure

Abstract

Plasmon-induced transparency (PIT) in a compact plasmonic resonator structure, which consists of a metal– dielectric–metal waveguide with an aperture-coupled square cavity and a slot resonator, is investigated theoretically and numerically. We find the transparency window and the delay of slow light in this structure can be controlled at a fixed wavelength… (More)
