HIGH-TEMPERATURE THERMAL PHOTONICS
RESUMO
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, spectroscopy, and sensing. We review the field of high-temperature thermal photonics, which aims to control the spectrum, polarization, tunability, switchability, and directionality of heat radiation from engineered materials in extreme environments. We summarize the candidate materials that are being pursued by the community that have simultaneous polaritonic/plasmonic properties as well as high-temperature stability. We also provide a detailed discussion of common photonic platforms, including metagratings, photonic crystals, and metamaterials used for thermal emission engineering. We review broad applications, including thermophotovoltaics, high-temperature radiative cooling, thermal radiation sources, and noisy nanoscale thermal devices. By providing an overview of the recent achievements in this field, we hope this review can accelerate progress to overcome major outstanding problems in modern thermal engineering.
