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)…
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…
Machine Learning enables Design of On-chip Integrated Silicon T-junctions with footprint of 1.2 m x 1.2 m
Sourangsu Banerji, Apratim Majumder, Alex Hamrick +2
To date, various optimization algorithms have been employed to design and improve the performance of nanophotonic structures. Here, we propose to utilize a machine-learning algorit…
VOC Sensing Using Batch-fabricated Temperature Compensated Self-Leveling Microstructures
Rugved Likhite, Aishwaryadev Banerjee, Apratim Majumder +3
We present the design, fabrication, and response of a low-power, polymer-based VOC sensor based on the self-leveling of mechanically leveraged structures. The device utilizes folde…
