Reconfigurable Curved Beams at Terahertz Frequencies Using Inverse-Designed Bilayer Diffractive Structures
Wei Jia, Miguel Gomez, Steve Blair +1
Curved electromagnetic beams at terahertz (THz) frequencies have recently emerged as a powerful example of wavefront engineering, with applications in imaging and high-capacity wir…
Holographic Mapping of Orbital Angular Momentum Using a Terahertz Diffractive Optical Neural Network
Wei Jia, Miguel Gomez, Steve Blair +1
Using orbital angular momentum (OAM) in the terahertz (THz) range provides a new degree of freedom for communication and imaging systems. This study presents a compact diffractive…
Inconsistencies of metalens performance and comparison with conventional diffractive optics
Rajesh Menon, Berardi Sensale-Rodriguez
We posit that inconsistent interpretations of experimental data have led to inaccurate claims on metalens focusing efficiencies. By performing a meta-analysis,we show that extraord…
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…
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…
