Localized Modes in Metamaterial-Dielectric Photonic Crystals with a Dielectric-Superconductor Pair Defect

Abstract

Transmission coefficient and dispersion relation are calculated for a one-dimensional photonic crystal of alternating dielectric-metamaterial slabs with a dielectricsuperconductor pair defect. The presence of the superconductor slab in the pair defect layer leads to a strong depletion of the TM transmission coefficient in a frequency range close to the edges of the non-Bragg gap and around the characteristic resonance frequency of the superconductor and introduces TM electromagnetic modes inside such gap. The features of the arising modes depend on the relation between the thicknesses of the layers involved in the defect and a low-frequency mode can arise from the lowfrequency continuum of the bulk metamaterial modes at a non-zero in-plane wave vector.

One-Dimensional Photonic Crystals With the Superconducting Defects

“…The influence of a complex defect layer (composed of SC and dielectric sublayers) as a spacer between two different PCs was studied in [20]. The localized modes in a metamaterial-dielectric PC with a dielectric-SC pair defect were investigated in [21]. The behavior of a DM inside a PBG depending on position (SC-dielectric and dielectric-SC) in a 1D PC was analyzed in [22].…”

Analysis of Transmission Properties in a Photonic Quantum Well Containing Superconducting Materials

“…PCs containing superconductors and dielectric are generally called the superconductor-dielectric photonic crystals (SDPCs) which have attracted much attention in the past decade [15][16][17][18][19][20]. More recently, the use of superconducting thin film as a defect layer in PC has shown that it can be a tuning agent in a transmission filter [21][22][23][24][25]. That is, the position of transmission peak can be changed by the variation of thickness in superconducting thin film.…”
