Investigation of Band Gap Width in Ternary 1D Photonic Crystal with Left-Handed Layer

Abstract

In this paper, we investigate the variation of band gap width in a ternary 1D photonic crystal with a left--handed layer versus variation of thicknesses and refractive index of second layers. We study these variations in two states, normal and oblique incidents for both TE and TM polarizations. We observe that the variations of band gap width versus thickness of layers are sensitive to the refractive index of second layers. For oblique incident both of variations are shifted towards the large/small frequencies by increasing the incident angles in TE/TM polarization, respectively.

“…The PBG modification with changing the layer thicknesses and the refractive indices in a ternary PC with a left-handed medium has been studied in Ref. [10], including the cases of oblique incidence of TE-and TM-polarized light.…”

“…In a recent work, the band gap in a photonic crystal consisting of dielectric/metal/dielectric was shown to be enlarged due to the metal layer [17]. The variation of the band gap width in a periodic photonic crystal with a negative-index material was investigated [18]. An omnidirectional photonic band gap in a photonic crystal having the structure dielectric/plasma layer/dielectric was investigated using the transfer matrix method [19].…”
