Tamm Plasmon Resonance as Optical Fingerprint of Silver/Bacteria Interaction

“…In any case, these results prompted us to the investigation of Tamm plasmons (TPs) which are electromagnetic modes confined between a DBR and a noble metal layer (i.e., gold or silver). − The TP mode can be experimentally observed as a narrow resonance peak (dip) in the transmission (reflection) spectrum of a sample at wavelengths within the band gap of 1DPC . In contrast to localized surface plasmons resonances, TPs are polarization independent and can be excited with high quality factor at normal incidence angle, without the need for phase-matching techniques like a grating or prism coupling. , Beside this advantageous operative feature, the relative simplicity of the planar structure necessary to achieve the TP resonance lends itself to both facile fabrication (i.e., spin casting or sol–gel deposition , ) and large-scale fabrication procedures. So far, TPs have been utilized for many purposes, including lasing, modification of light-matter interaction, − radiative coolers, thermal emitters, and optical sensors, ,− among others.…”

Hybrid Tamm plasmon resonance excitation towards a simple and efficient biomedical detector of NaI solution

“…In this context, the excitation of Tamm plasmon (TP) resonance at the interface between a thin metallic layer of denite thickness and a multilayer periodic structure like photonic crystals (PCs) could be the mainstay for the above-mentioned sensors. [1][2][3][4][5] Hence, PCs as articial periodic designs in one, two, or three dimensions are capable of the formation of some stop frequency bands along the spectrum of the incident electromagnetic waves. [6][7][8] These bands are likely dened as photonic band gaps (PBGs).…”

“…[33][34][35] In this regard, the excitation of TP resonance modes based on PC structures received considerable attention on both theoretical and experimental levels. 1,[33][34][35][36][37][38][39][40] In this research, we intend to present a theoretical verication for the detection of NaI solution with different concentrations in the vicinity of TP resonance. Also, this research study is introduced for sensing NaI concentrations due to the signicant importance of NaI in a Physics Department, College of Science, Jouf University, P.O.…”

“…In this regard, these types of sensors are mainly designed and fabricated based on the changes in optical characteristics such as reflectivity, transmittivity and absorbance. 1 These changes could be generated as a result of specific chemical, physical or biological characteristics. Therefore, many of the complex interactions could be simply analyzed and clarified using these simple instruments.…”
