Imaging over an unlimited bandwidth with a single diffractive surface
Sourangsu Banerji, Monjurul Meem, Apratim Majumder +2
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…
Broadband imaging with one planar diffractive lens
Nabil Mohammad, Monjurul Meem, Bing Shen +1
We demonstrate imaging over the visible band using a single planar diffractive lens. This is enabled via multi-level diffractive optics that is designed to focus over a broad wavel…
An Ultra-compact Nanophotonic Optical Modulator using Multi-State Topological Optimization
Apratim Majumder, Bing Shen, Randy Polson +2
Optical modulators are one of the most important elements of photonic circuits. Here, we designed, fabricated and characterized a nanophotonic all optical modulator (NOM) in silico…
Lensless-camera based machine learning for image classification
Ganghun Kim, Stefan Kapetanovic, Rachael Palmer +1
Machine learning (ML) has been widely applied to image classification. Here, we extend this application to data generated by a camera comprised of only a standard CMOS image sensor…
