Periodic structure containing host hyperbolic material for nano-guiding, sensing and imaging applications

Abstract

In this simulation work, we have theoretically proposed a design of hyperbolic material-based ternary multilayer structure of plasma photonic crystal comprised of dielectrics and plasma materials. The optical properties have been analyzed with the help of transfer matrix method (TMM). The obtained spectra of reflection, transmission and absorption drawn with variation in filling fraction for the hyperbolic meta-material-based PC, are analyzed. By varying the filling fraction as f=0.1,0.2,0.3,0.4, it is found that at normalized frequency range, above 0.2, reflection is negligible. Thereafter, in higher normalized frequency, there exist a bandgap in a normalized frequency range 0.82–1.35. From the transmission spectra, it is noted that the transmission is nearly zero in lower normalized frequency range 0.0–0.2, then the transmission increases, and further decreases with formation of a bandgap. On the other-hand, the absorption is nearly 90% at lower normalized frequency region; and at higher normalized frequency, a zero-absorption band is obtained. Thus, we obtain an enlarged PBG in the normalized frequency range 0.82 to 1.35, where the zero-absorptionband for normal incidence also occurs at low frequency. The absorption increases with an increase in the filling fraction. All these results are in a good agreement with those reported earlier by the researchers. The insights of the present article can be employed in design of tunable optical filter, optical window, optical logic gate, broadband reflector, and absorption-based devices. The article can also be useful in the investigations on nano-guiding, sensing and imaging applications.
