Lower bound on the thickness of broadband dielectric mirrors
Mikhail A. Kats
We present a lower bound on the total physical thickness of a lossless, non-dispersive dielectric mirror for a given minimum reflectance across a wavelength band. The bound is base…
Metasurfaces for neutral-atom trapping
Chengyu Fang, Minjeong Kim, Mark Saffman +2
Trapped neutral atoms are one of the leading platforms for quantum information technologies, in particular for quantum computing, but scaling them to array sizes needed for utility…
Material selection for mid-infrared thin-film coatings and windows
Jin-Woo Cho, Tanuj Kumar, Hongyan Mei +1
We summarized the room-temperature optical properties for infrared-transparent materials, defining transparency windows for two different applications: thin-film coatings (absorpti…
Silicon-on-sapphire metasurfaces generate arrays of dark and bright traps for neutral atoms
Chengyu Fang, Minjeong Kim, Hongyan Mei +10
We demonstrated crystalline silicon-on-sapphire (c-SOS) metasurfaces that convert a Gaussian beam into arrays of complex optical traps, including arrays of optical bottle beams tha…
Anti-reflection coatings for highly anisotropic materials in the mid infrared
Hongyan Mei, Jin-Woo Cho, Jae-Seon Yu +6
We develop and optimize thin anti-reflection coatings (ARCs) for highly anisotropic materials in the mid infrared. Unlike conventional ARCs that assume nearly isotropic refractive…
Passive radiative cooling using temperature-dependent emissivity can sometimes outperform static emitters
Yeonghoon Jin, Jin-Woo Cho, Mikhail A. Kats
In passive sky-facing radiative cooling, wavelength-selective thermal emitters in the atmospheric transparency window of 8-13 m can reach lower temperatures compared to broadban…
