Computational modeling and numerical Investigation of a chalcogenide glass-based Graded-Index Photonic Crystal Fiber (GI-PCF) for the mid-infrared region has been put forth. Our proposed structure has a solid core and hence index-guided mechanism of

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.

In this paper, we report Fano resonance in the dielectric disk and rod cuboidal nanoparticles. In these nanoparticles, forward to backward scattering ratio is enhanced as compared to cubic or other symmetrical nanoparticles. Electric and magnetic dip

In this paper, we have numerically designed a golden spiral photonic crystal fiber using tellurite glass for supercontinuum generation. Dispersion engineering technique has been used for the optimization of geometrical parameters of the fiber. At a p
