“…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]. Moreover, by these materials TPPs can be formed when the real part of the permittivity is near-zero (ENZ) in visible wavelength range.…”

We demonstrated the possibility of using transparent conducting oxides (AZO, GZO, ITO) to form Tamm plasmon polaritons in the near-infrared spectral range where the permitivity of oxides is near-zero. The spectral properties of the structures have been investigated in the framework of the temporal coupled mode theory and confirmed by transfer matrix method. It was found that in the critical coupling conditions the maximal Q-factor of a Tamm plasmon polariton is achieved when photonic crystal is conjugated with the AZO film, while at the conjugation with the ITO films the broadest spectral line is obtained. The sensitivity of the wavelength and spectral width of the Tamm plasmon polariton to changes of the oxide film thickness, the bulk concentration of a dopand and the angle of incidence are demonstrated.

“…The result of interaction between the radiation field and surface plasmon excitation is a Tamm plasmon polariton (TPP) [2], which is observed in experiments as a narrow peak in the energy spectra of a sample [3][4][5]. As was shown in [6][7][8][9][10], the materials with the negative permittivity ( ε eff (ω) < 0) adjacent to a PhC can be both metallic films and nanocomposites with the resonant frequency dispersion.…”

Abstract:The spectral properties of a one-dimensional photonic crystal bounded by a resonant absorbing nanocomposite layer with the near-zero permittivity have been studied. The problem of calculating the transmittance, reflectance, and absorptance spectra of such structures at the normal and oblique incidence of light has been solved. It is shown that, depending on the permittivity sign near zero, the nanocomposite is characterized by either metallic or dielectric properties. The possibility of simultaneous formation of the Tamm plasmon polariton at the photonic crystal/metallic nanocomposite interface and the localized state similar to the defect mode with the field intensity maximum inside the dielectric nanocomposite layer is demonstrated. Specific features of field localization at the Tamm plasmon polariton and defect mode frequencies are analyzed.

“…1a. Optical modes arising from the periodicity disturbance at the PC surface are often referred as optical Tamm states [26][27][28]. A crucial property of a PC is that its surface mode is concentrated near the air interface [29][30][31][32], and this is extremely important to form high temperature gradient.…”
