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…
All-passive upconversion of incoherent near-infrared light at intensities down to 10 W/cm
Rabeeya Hamid, Demeng Feng, Pournima Narayanan +10
Frequency upconversion, which converts low-energy photons into higher-energy ones, typically requires intense coherent illumination to drive nonlinear processes or the use of exter…
Electrically tunable VO2-metal metasurface for mid-infrared switching, limiting, and nonlinear isolation
Jonathan King, Chenghao Wan, Tae Joon Park +4
We demonstrate an electrically controlled metal-VO2 metasurface for the mid-wave infrared that simultaneously functions as a tunable optical switch, an optical limiter with a tunab…
