“…Once the dielectric function is known, the dispersion properties of the SPP can be deduced from the surface polariton (SP) dispersion relation. Taking the anisotropy of the material into account, the SP dispersion relation of a two layer system can be expressed as [21]:…”

The lattice vibrational properties of wurtzite ternary mixed crystal aluminium indium nitride (AlxIn1-xN) are investigated thoroughly using modified random element iso-displacement (MREI) model and Born-Huang procedure. MREI model, which considers the nearest neighbour interactions, is used to predict the composition dependence of longitudinal and transverse optical phonon frequencies. For AlxIn1-xN alloy, oscillator strength of its weak mode is sufficiently significant for composition range of 0 < x < 0.4. As a result, AlxIn1-xN alloy is deduced to exhibit mixed-mode behaviour. Finally, the calculated dielectric functions for the entire composition range (0 < x < 1) are used to simulate the surface phonon polariton characteristics of the AlxIn1-xN alloy.

“…For SPhPs on natural crystal surfaces, such as α-quartz, the polariton resonant frequencies are generally on the order of terahertz [19][20][21] and are difficult to tune. A piezoelectric superlattice (PSL) is a metamaterial with oppositely poled adjacent domains of a piezoelectric crystal [22,23].…”

Surface phonon polaritons on anisotropic piezoelectric superlattices

A theoretical study of surface phonon polaritons (SPhPs) on periodically poled lithium niobate and periodically poled lithium tantalate surfaces is presented. We calculate the dielectric response for six different superlattice orientations and the associated SPhP dispersion relations. Our study of SPhPs accounts for the anisotropic nature of the dielectric response of the semi-infinite piezoelectric superlattices. We find that two different types of SPhPs can be supported. The first type consists of real surface dipole oscillations coupled to photons. The second type consists of virtual surface dipole oscillations driven by the incident photons. The dependence of the SPhPs on temperature and superlattice geometry is addressed. The use of these metamaterial excitations is discussed in the context of hybrid quantum systems.

“…[16] Here, we give more comprehensive discussions on the field patterns and their propagation features associated with the hybrid coupling with graphene, especially when the properties of graphene are varied. For AlN and ZnO their semi-conductor and optoelectronics properties have been widely investigated in the field of material science, [17,18] while their EM characteristics on surface plasmon polartitons (SPPs), in particular hybridizing with another plasmonic layer are less discussed. It is scientifically and also practically instrumental to explore their optical features as potential plasmonic material candidates for novel photonic phenomena or functionalities.…”

Plasmon–phonon coupling in graphene–hyperbolic bilayer heterostructures

Polar dielectrics are important optical materials enabling the subwavelength manipulation of light in infrared due to their capability to excite phonon polaritons. In practice, it is highly desired to actively modify these hyperbolic phonon polaritons (HPPs) to optimize or tune the response of the device. In this work, we investigate the plasmonic material, a monolayer graphene, and study its hybrid structure with three kinds of hyperbolic thin films grown on SiO 2 substrate. The inter-mode hybridization and their tunability have been thoroughly clarified from both the band dispersions and the mode patterns numerically calculated through a transfer matrix method. Our results show that these hybrid multilayer structures are of strong potentials for applications in plasmonic waveguides, modulators and detectors in infrared.
