HIGH-TEMPERATURE THERMAL PHOTONICS

Controlling and detecting thermal radiation is of vital importance for varied applications ranging from energy conversion systems and nanoscale information processing devices to infrared imaging,

High Temperature Polaritons in Ceramic Nanotube Antennas.

The high frequency optical phonons present in BNNTs are Leveraged to create strong mid IR thermal antenna emitters at high temperatures (938K) and it is shown that the antenna behavior can be observed even in a disordered system.

Probing Near-Field Thermal Emission of Localized Surface Phonons from Silicon Carbide Nanopillars

Thermal emission of localized surface phonons (LSPhs) from nanostructures of polaritonic materials is a promising mechanism for tuning the spectrum of near-field thermal radiation. Previous studies

Far-field thermal radiation from short-pitch silicon-carbide nanopillar arrays

Silicon carbide (SiC) supports surface phonons in the infrared region of the electromagnetic spectrum where these modes can be thermally emitted. Additionally, the magnitude, spectrum, and direction

Effects of anisotropy, morphology, and interparticle coupling on the far-infrared optical modes of randomly oriented ZnO nanoparticles

Polar dielectric nanoparticles (NPs) with uniaxial anisotropy support two-surface phonon polariton modes inside a reststrahlen band. The effective permittivity of a randomly orientated ensemble of

Highly directional radiation generated by a tungsten thermal source.

We report the design of a tungsten thermal source with extraordinarily high directivity in the near infrared, comparable to the directivity of a CO2 laser. This high directivity is the signature of

Dual-wavelength orthogonally polarized radiation generated by a tungsten thermal source.

A two-dimensional orthogonally-crossed shallow grating is proposed to produce an orthog onally-polarized dual-wavelength radiation with the emissivity as high as 78% and 91% from a single surface.

Broadband super-planckian thermal emission from hyperbolic metamaterials

We develop fluctuational electrodynamics of hyperbolic metamaterials (HMMs) and establish broadband near-field thermal emission beyond the black-body limit. We predict thermal topological transitions

Coherent thermal infrared emission by two-dimensional silicon carbide gratings

The thermal emission of cross-slit silicon carbide grating is studied in the Restrahlen region over all emission angles. We show experimentally that the thermal excitation of surface-phonon

Thermal emission of two-color polarized infrared waves from integrated plasmon cavities

We have demonstrated that orthogonally polarized two-color infrared waves thermally emitted from gratings integrated onto a single Au chip open a way for simple and efficient chemical analysis. Each

Efficient infrared thermal emitters based on low-albedo polaritonic meta-surfaces

A low-albedo all-semiconductor meta-surface with spectrally selective absorption peaks is demonstrated. By engineering the dimensions and shapes of the semiconductor antennas comprising the

Degree of polarization of thermal light emitted by gratings supporting surface waves.

It is found that a source can be quasi isotropic from the point of view of the intensity but strongly anisotropic for polarized light, and that the degree of polarization can vary between 0 and 1, depending on directions.

Taming the blackbody with infrared metamaterials as selective thermal emitters.

This Letter demonstrates, for the first time, selective thermal emitters based on metamaterial perfect absorbers and finds that emissivity and absorptivity agree very well as predicted by Kirchhoff's law of thermal radiation.

Coherent spontaneous emission of light by thermal sources

The emission of light by a material at temperature T has been shown recently to be coherent in the near field. These properties were attributed to the thermal excitation of surface polaritons. We

The possibility of controlling near-field radiative heat transfer with the use of silicon carbide thin films supporting surface phonon–polaritons in the infrared spectrum is explored. For this
