“…Recent experiments on nanoengineered structures, however, have begun to challenge these notions, showing that blackbody emission can be coherent and unidirectional, with narrow spectral features. These structures have included patterned gratings on metal or silicon carbide surfaces that can control the directionality and coherence of thermal radiation 1,2 , as well as photonic crystals 3 , size-tunable Mie resonances 4 and frequency-selective metasurfaces 5 , which can tune the spectral profile. Progress has also been made in demonstrating dynamic control of thermal radiation through in situ modification of material emissivity.…”

Electronic modulation of infrared radiation in graphene plasmonic resonators

All matter at finite temperatures emits electromagnetic radiation due to the thermally induced motion of particles and quasiparticles. Dynamic control of this radiation could enable the design of novel infrared sources; however, the spectral characteristics of the radiated power are dictated by the electromagnetic energy density and emissivity, which are ordinarily fixed properties of the material and temperature. Here we experimentally demonstrate tunable electronic control of blackbody emission from graphene plasmonic resonators on a silicon nitride substrate. It is shown that the graphene resonators produce antenna-coupled blackbody radiation, which manifests as narrow spectral emission peaks in the mid-infrared. By continuously varying the nanoresonator carrier density, the frequency and intensity of these spectral features can be modulated via an electrostatic gate. This work opens the door for future devices that may control blackbody radiation at timescales beyond the limits of conventional thermo-optic modulation.

“…From a fundamental physics perspective, with the capability to tailor lightmatter interactions, nanophotonic structures can enable thermal emission behaviors that are drastically different from those of conventional bulk emitters [12][13][14][15][16][17][18][19][20][21][22][23]. For example, while blackbody emitters are typically considered to be incoherent with a total emission power limited by the Stephan-Boltzman law, nanophotonic emitters can be highly coherent [6,20,22] or have emission beyond the blackbody limit [4,19].…”

“…As their fabrication is considerably simpler in comparison with volumetric metamaterials, metasurfaces were the first to find practical applications at optical frequencies ranging from light manipulation [5][6][7][8][9][10] and sensing of minute analyte quantities [10][11][12] to nonlinear optics 13,14 , spectrally selective thermal emission 15 and even low-threshold lasing 16 . Many of these applications require photonic structures characterized by their highly spectrally selective response (corresponding to high-quality factor Q), miniaturized format (preferably on the scale of no more than several wavelengths) and the convenience and high efficiency of far-field light coupling.…”

Spectrally selective chiral silicon metasurfaces based on infrared Fano resonances

et al. 2014

Metamaterials and metasurfaces represent a remarkably versatile platform for light manipulation, biological and chemical sensing, and nonlinear optics. Many of these applications rely on the resonant nature of metamaterials, which is the basis for extreme spectrally selective concentration of optical energy in the near field. In addition, metamaterial-based optical devices lend themselves to considerable miniaturization because of their subwavelength features. This additional advantage sets metamaterials apart from their predecessors, photonic crystals, which achieve spectral selectivity through their longrange periodicity. Unfortunately, spectral selectivity of the overwhelming majority of metamaterials that are made of metals is severely limited by high plasmonic losses. Here we propose and demonstrate Fano-resonant all-dielectric metasurfaces supporting optical resonances with quality factors Q4100 that are based on CMOS-compatible materials: silicon and its oxide. We also demonstrate that these infrared metasurfaces exhibit extreme planar chirality, opening exciting possibilities for efficient ultrathin circular polarizers and narrow-band thermal emitters of circularly polarized radiation.
