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…
Two-coil Wireless Power Transfer System Configured in Series-Series Topology: Fundamental Dynamics and Limitations on Transmitted Power
Binh Duc Truong, Thuy Thi-Thien Le, Berardi Sensale-Rodriguez
The dynamics and performance of a two-coil resonant coupled wireless power transfer system are investigated. At high coupling, the frequency-splitting phenomenon occurs, in which t…
The anisotropic quasi-static permittivity of single-crystal beta-Ga2O3
Prashanth Gopalan, Sean Knight, Ashish Chanana +11
The quasi-static anisotropic permittivity parameters of electrically insulating gallium oxide (beta-Ga2O3) were determined by terahertz spectroscopy. Polarization-resolved frequenc…
Role of Fabrication Errors and Refractive Index on Multilevel Diffractive Lens Performance
Sourangsu Banerji, Jacqueline Cooke, Berardi Sensale-Rodriguez
Multilevel diffractive lenses (MDLs) have emerged as an alternative to both conventional diffractive optical elements (DOEs) and metalenses for applications ranging from imaging to…
Super-resolution imaging with an achromatic multi-level diffractive microlens array
Sourangsu Banerji, Monjurul Meem, Apratim Majumder +2
Compound eyes found in insects provide intriguing sources of biological inspiration for miniaturized imaging systems. Inspired by such insect eye structures, we demonstrate an ultr…
An inverse designed achromatic flat lens operating in the ultraviolet
Sourangsu Banerji, Berardi Sensale Rodriguez
We demonstrate an inverse designed achromatic, flat, polarization-insensitive diffractive optic element, i.e., multilevel diffractive lens (MDL), operating across a broadband range…
