Multiple responses of TPP-assisted near-perfect absorption in metal/Fibonacci quasiperiodic photonic crystal

Abstract

Absorption properties in one-dimensional quasiperiodic photonic crystal composed of a thin metallic layer and dielectric Fibonacci multilayers are investigated. It is found that a large number of photonic stopbands can occur at the dielectric Fibonacci multilayers. Tamm plasmon polaritons (TPPs) with the frequencies locating at each photonic stopband are excited at the interface between the metallic layer and the dielectric layer, leading to almost perfect absorption for the energy of incident wave. By adjusting the length of dielectric layer with higher refractive-index or the Fibonacci order, the number of absorption peaks can be tuned effectively and enlarged significantly.

Quasiperiodic one-dimensional photonic crystals with adjustable multiple photonic bandgaps

“…So far, QPPCs of several kinds have been investigated; among them are Fibonacci, Thue-Morse, Rudin-Shapiro, double periodic, octonacci, Cantor and Pell-like structures [4]. Earlier, deterministic PCs were successfully used for optical filtering, multi-frequency terahertz manipulation, near-perfect absorption and omnidirectional reflection, photoluminescence emission enhancement [5][6][7][8][9][10][11][12]. Fibonacci and Thue-Morse-like photonic structures have been reported for the Bloch-like surface waves [13] and multimode photon-exciton coupling [14], which represent a significant advantage compared to periodic PC counterparts.…”

Transparent conductive oxides for the epsilon-near-zero Tamm plasmon polaritons

“…The spectral properties of the TPP can be controlled by varying the lattice parameters [5] or metallic film material [6]. The TPPs gave rise to the fundamentally new type of devices, which includes absorbers [7][8][9][10], switches [11], organic solar cells [12], thermal emitters [13,14], sensors [15,16] and spontaneous emission amplifiers [17]. In addition to metal, the resonant nanocomposite materials can be used as a material with negative dielectric permittivity for TPP excitation [18][19][20][21][22].…”

Two Types of Localized States in a Photonic Crystal Bounded by an Epsilon near Zero Nanocomposite

“…Theoretical and experimental investigations of the properties of TPPs allowed them to be used as the basis of a fundamentally new class of devices, including absorbers [11][12][13][14], switchers [15], organic solar cells [16], thermal emitters [17,18], sensors [19][20][21], and spontaneous radiation amplifiers [22]. The high degree of field localization at the TPP frequency makes it possible to reduce the threshold of generation of nonlinear effects [23][24][25] and implement the extremely high light transmission through a nanohole [26].…”
