“…However, the crucial challenge of precisely controlling and manipulating the electricfield enhancement of TPP modes at the interface of metal and DBR still persists [9,10,17]. It is interesting to note that a few recent studies have focused on the critical nature of coupling of free-space plane waves to TPP modes with primary focus on bulk impedances of constituent media [18][19][20]. In an interesting investigation, a novel approach based on admittance loci was proposed by Chang et al towards analyzing the dependence of TPP resonance on DBR architecture as well as tuning the resonance coupling efficiency [18].…”

Tamm plasmon-polaritons (TPPs), formed at the interface of a plasmon-active metal and a distributed Bragg reflector (DBR), are characterized by sharp resonances in the reflection spectrum. The features of these sharp TPP resonances are primarily dictated by the structural parameters as well as by the nature of materials of the constituent DBR and metal. In the present investigation, we experimentally and theoretically analyze the role played by the DBR parameters and the metal layer thickness in determining the efficiency of TPP-mode excitation using plane waves. The findings reveal that the minimum in the reflection spectrum depicting the TPP resonance is strongly influenced by the thickness of plasmon-active metal film as well as the number of DBR unit cells. In fact, there exists an optimum combination of the geometrical parameters for achieving a maximum coupling to TPP modes. A brief theoretical analysis elucidating the underlying mechanism behind such observations is also presented so as to optimally design TPP-based architectures for different applications.

“…In the above-mentioned formulas (2) and (3), in the case of filling ϕ¼901 or θ¼01 or 901, ϕ and θ cannot be obtained individually. Then, when the polarized light from the lighting optical system is emitted to the object with the incidence angle α, the refractive index n x 0 on the appearance of x-axis orientations and n y 0 on the appearance of y-axis orientations in which the incident radiation proceeds in the object is expressed with the following formulae (6) and (7).…”

“…Especially, control of the direction of c-axis crystallography with which other axes called the a-or b-axis are homogeneous plays a critical role in many technologically pertinent areas, ranging from the control of quantum efficiency in an electro-optical device [1][2][3][4][5][6][7][8] to use as a compensator for a phase difference in optical films with an LCD [9][10][11][12]. In all cases, this crystal axis needs to be controlled.…”
