3D-Patterned Inverse-Designed Mid-Infrared Metaoptics
Gregory Roberts, Conner Ballew, Tianzhe Zheng +4
Modern imaging systems can be enhanced in efficiency, compactness, and application through introduction of multilayer nanopatterned structures for manipulation of light based on it…
Monolithic all-Silicon Flat lens for broadband LWIR Imaging
Orrin Kigner, Monjurul Meem, Brian Baker +4
We designed, fabricated and characterized a flat multi-level diffractive lens (MDL) comprised of only silicon with diameter = 15.2mm, focal length of 19mm, and operating over the l…
Experimental Demonstration of Dynamic Thermal Regulation using Vanadium Dioxide Thin Films
Ahmed M. Morsy, Michael T. Barako, Vladan Jankovic +6
We present an experimental demonstration of passive, dynamic thermal regulation in a solid-state system with temperature-dependent thermal emissivity switching. We achieve this eff…
Imaging from the Visible to the Longwave Infrared wavelengths via an inverse-designed flat lens
Monjurul Meem, Sourangsu Banerji, Apratim Majumder +4
It is generally assumed that correcting chromatic aberrations in imaging requires optical elements. Here, we show that by allowing the phase in the image plane to be a free paramet…
Experimental Demonstration of >230° Phase Modulation in Gate-Tunable Graphene-Gold Reconfigurable Mid-Infrared Metasurfaces
Michelle C. Sherrott, Philip W. C. Hon, Katherine T. Fountaine +5
Metasurfaces offer significant potential to control far-field light propagation through the engineering of amplitude, polarization, and phase at an interface. We report here phase…
