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…
Machine Learning enables Ultra-Compact Integrated Photonics through Silicon-Nanopattern Digital Metamaterials
Sourangsu Banerji, Apratim Majumder, Alex Hamrick +2
In this work, we demonstrate three ultra-compact integrated-photonics devices, which are designed via a machine-learning algorithm coupled with finite-difference time-domain (FDTD)…
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…
Inverse-designed flat lens for imaging in the visible & near-infrared with diameter > 3mm and NA=0.3
Monjurul Meem, Sourangsu Banerji, Apratim Majumder +4
It is generally thought that correcting chromatic aberrations in imaging requires multiple surfaces. Here, we show that by allowing the phase in the image plane of a flat lens to b…
