Abstract:

We report a device that provides coherent emission of phonon polaritons, a mixed state between photons and optical phonons in an ionic crystal. An electrically pumped GaInAs/AlInAs quantum cascade structure provides intersubband gain into the polariton mode at λ = 26.3 μm, allowing self-oscillations close to the longitudinal optical phonon energy of AlAs. Because of the large computed phonon fraction of the polariton of 65%, the emission appears directly on a Raman spectrum measurement, exhibiting a Stokes and anti-Stokes component with the expected shift of 48 meV.

Abstract:

We show that the photon quadrature squeezing, the phonon quadrature squeezing and the polariton quadrature squeezing can exist in a model polariton system at low temperature with the photons and the phonons initially being prepared in the coherent states and the thermal states respectively and the distributions of the photons, the phonons and the polaritons can be sub-Poissonian. We also show that all these effects strongly depend on the temperature.

Abstract:

An analytic expression is obtained for determining the frequency and temperature dependences of polariton damping in a monatomic crystal for an arbitrary form of the coupling function describing the interaction between a polariton and an acoustic phonon. Calculations are made in a one-phonon approximation for weak coupling in the case of a linear dependence of the energy of acoustic phonons on the wave vector and a polariton dispersion of the E(k)=ET+ℏ2k2/2m+δE/1−ℏ2k2c2ε∞ET2−1 where ET is the energy of transverse vibrations.

Polaritons can provide strong optical field enhancement allowing them to boost light–matter interaction. Here, we experimentally observe enhancement in mid-infrared second-harmonic generation (SHG) using grating-coupled surface phonon polaritons of the 6H-SiC surface. In our experiment, we measure the SHG along the polariton dispersion by changing the incidence angle of the excitation beam. We observe hybridization between the propagating surface phonon polaritons and localized plasmon resonances in the gold grating, evidenced by the modification of the polariton dispersion as we change the ar

Abstract:

The polar phonon polariton modes in a wurtzite thin-film structure have been theoretically investigated in the present paper. It has been confirmed that there are two types of phonon polariton modes, i.e., the surface phonon polariton (SPP) modes and the confined phonon polariton (CPP) modes in wurtzite thin-film systems. The frequency ranges of the SPP and CPP modes have been discussed in detail. The dispersive equations for the two types of polarition modes are also deduced. Numerical calculations on a GaN thin-film structure reveal that, for a given free wavenumber kt in x-direction, there

Abstract:

Phonon polaritons are guided hybrid modes of photons and optical phonons that can propagate on the surface of a polar dielectric. In this work, we show that the precise combination of confinement and bandwidth offered by phonon polaritons allows for the ability to create highly efficient sources of polariton pairs in the mid-IR/terahertz frequency ranges. Specifically, these polar dielectrics can cause emitters to preferentially decay by the emission of pairs of phonon polaritons, instead of the previously dominant single-photon emission. We show that such two-photon emission processes can occ

Abstract:

Specular infrared reflection spectra in the range of “residual rays” of the film and the substrate and in the case of the E⊥c orientation of the electric field have been simulated for the first time for thin MgxZn1−xO films deposited on optically anisotropic 6H-SiC substrates. The simulation was carried out making use of self-consistent parameters obtained earlier for magnesium oxide, zinc oxide, and silicon carbide single crystals. The film thickness and the Mg content x in the film are demonstrated to considerably distort the reflection spectra and to change the reflectivity of the MgxZn1−xO
