Abstract

We study the scattering, absorption and extinction of THz radiation by 2D plasmonic crystals formed by periodic arrays of semiconductor particles. The particles sustain localized surface plasmon resonances that can couple to diffracted orders of the array giving rise to hybrid plasmonic-photonic modes. These modes exhibit extraordinary extinction and narrow line widths. The coupling strength and, consequently, the extinction can be actively tuned by changing the carrier concentration in the semiconductor, which is achieved by optical pumping.
