In this article, a highly directive all-dielectric zero-index metamaterial (ZIM) based nanoantenna has been proposed which has the ability to directionally transmit the radiation from an isotropic quantum emitter. The zero-index metamaterial (ZIM) us

In this paper, the design of the cavity-based photonic crystal (PhC) ‘OR’ Gate has been proposed. The structure consists of three waveguides and two square resonators in a PhC composed of cylindrical rods of GaAs in air. The designed logic gate p

We report significant variation in chromatic dispersion from -165.085 to-1427.495 ps/nm-km at 4.9 µm wavelength by only varying hole-size of the first layer of Chalcogenide based Photonic crystal fiber in the Mid-Infrared range.
