“…These parameters are obtained from the previous publications. [16,30,31] ε ∞ ω LO /cm −1 ω TO /cm −1 γ LO /cm −1 γ TO /cm For the hybrid structure, we consider a 100-nm-thick hBN thin film as the hyperbolic layer. The resonant surface modes can be determined by the poles of the reflection coefficients and the mode dispersion patterns of the hybrid structure are obtained by plotting the imaginary part of the reflection coefficient r. [27,32] The results are given in Fig.…”

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.

“…Taking the free carriers and anisotropy into account, the dielectric function model of wurtzite ZnO can be expressed as the same as AlN. [31] However, we use a moderate damping constant when the single crystal ZnO is fabricated. In our calculation, the ZnO thickness is set to be 300 nm.…”
