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…
Free-form broadband flat lenses for visible imaging
Monjurul Meem, Apratim Majumder, Rajesh Menon
In the absence of separate apertures, the size and focal length of a lens determines both its resolution and light-collection ability defined by numerical-aperture (NA) and f/#, re…
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…
Large-area, high-NA Multi-level Diffractive Lens via inverse design
Monjurul Meem, Sourangsu Banerji, Christian Pies +3
Flat lenses enable thinner, lighter, and simpler imaging systems. However, large-area and high-NA flat lenses have been elusive due to computational and fabrication challenges. Her…
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…
