Gradient polaritonic surface with space-variant switchable light-matter interactions in 2D moire superlattices
Zhen-Bing Dai, Hua Fan, Vyacheslav Semenenko +7
Polaritons in two-dimensional (2D) materials provide unique opportunities for controlling light at nanoscales. Tailoring these polaritons via gradient polaritonic surfaces with spa…
Wavelength-by-wavelength temperature-independent thermal radiation utilizing an insulator-metal transition
Jonathan King, Alireza Shahsafi, Zhen Zhang +7
Both the magnitude and spectrum of the blackbody-radiation distribution change with temperature. Here, we designed the temperature-dependent spectral emissivity of a coating to cou…
Ultrathin broadband reflective optical limiter
Chenghao Wan, Zhen Zhang, Jad Salman +7
Optical limiters are nonlinear devices that feature decreasing transmittance with increasing incident optical intensity, and thus can protect sensitive components from high-intensi…
VO2 Nanocrystals for Designer Phase-Change Metamaterials
Jimmy John, Yael Gutierrez, Zhen Zhang +5
Subwavelength nanoparticles can support electromagnetic resonances with distinct features depending on their size, shape and nature. For example, electric and magnetic Mie resonanc…
Temperature-independent thermal radiation
Alireza Shahsafi, Patrick Roney, You Zhou +11
Thermal emission is the process by which all objects at non-zero temperatures emit light, and is well-described by the classic Planck, Kirchhoff, and Stefan-Boltzmann laws. For mos…
Optical properties of thin-film vanadium dioxide from the visible to the far infrared
Chenghao Wan, Zhen Zhang, David Woolf +13
The insulator-to-metal transition (IMT) in vanadium dioxide (VO2) can enable a variety of optics applications, including switching and modulation, optical limiting, and tuning of o…
