TOM 7 Thermal radiation and energy management

Anisotropic 2D layered materials for infrared phononics and polaritonics

Koray Aydin

Northwestern Univ., United States of America

In this talk, I will introduce MoO3 as an anisotropic photonic and polaritonic material. We designed and experimentally demonstrated an anisotropic polaritonic absorber and showed that one can couple to all phonon modes and address them individually either using structural tunability or polarization control of incident infrared radiation. By combining with VO2, we also demonstrated tunable infrared absorption at infrared wavelengths.

TOM 7 Thermal radiation and energy management

Using strong light-matter coupling to modify energy transfer

Johannes Feist

Universidad Autónoma de Madrid, Spain

When light modes and material excitations are coupled sufficiently strongly, they hybridize to form mixed light-matter excitations, so-called polaritons. Polaritons inherit properties from both their constituents, which can be exploited to obtain novel functionalities not present in either of the uncoupled systems. In particular, I will discuss how polariton formation can be used to tune the absorption spectrum of solar thermal fuels as well as modify the energy transfer between and emission properties of different molecular species.

There is an increasing interest in the infrared stealth property of vanadium dioxide. In this paper monoclinic vanadium dioxide paints have been applied to prepare coated cotton fabrics. The infrared emissivity measured by thermography in the 8–14 μm wavelength range reveals a drop of emissivity of about 10% of the coated fabrics as the temperature increases from 40 °C to 80 °C, opening a new strategy to manipulate the infrared emission of smart textiles
