Solid-Immersion Metalenses for Infrared Focal Plane Arrays
Shuyan Zhang, Alexander Soibel, Sam A. Keo +6
Novel optical components based on metasurfaces (metalenses) offer a new methodology for microlens arrays. In particular, metalens arrays have the potential of being monolithically…
Radiative thermal runaway due to negative differential thermal emission across a solid-solid phase transition
David M. Bierman, Andrej Lenert, Mikhail A. Kats +6
Thermal runaway occurs when a rise in system temperature results in heat generation rates exceeding dissipation rates. Here we demonstrate that thermal runaway occurs in thermal ra…
Dynamic metasurface lens based on MEMS Technology
Tapashree Roy, Shuyan Zhang, Il Woong Jung +3
In the recent years, metasurfaces, being flat and lightweight, have been designed to replace bulky optical components with various functions. We demonstrate a monolithic Micro-Elec…
Large Area Metalenses: Design, Characterization, and Mass Manufacturing
Alan She, Shuyan Zhang, Samuel Shian +2
Optical components, such as lenses, have traditionally been made in the bulk form by shaping glass or other transparent materials. Recent advances in metasurfaces provide a new bas…
Large Area Electrically Tunable Lenses Based on Metasurfaces and Dielectric Elastomer Actuators
Alan She, Shuyan Zhang, Samuel Shian +2
Tunable optical devices, in particular, varifocal lenses, have important applications in various fields, including imaging and adaptive vision. Recent advances in metasurfaces, whi…
Vanadium dioxide as a natural disordered metamaterial: perfect thermal emission and large broadband negative differential thermal emittance
Mikhail A. Kats, Romain Blanchard, Shuyan Zhang +4
We experimentally demonstrate that a thin (~150 nm) film of vanadium dioxide (VO2) deposited on sapphire has an anomalous thermal emittance profile when heated, which arises due to…
