Broadband Content-Adaptive Moiré Meta-spectrometer
Arnab Ghosh, Johannes E. Fröch, Arka Majumdar +1
Optical spectroscopy underpins material characterization, chemical sensing, and astronomy, but conventional instruments face a rigid trade-off between footprint, spectral range, an…
All-Dielectric Metasurface with a Two-Dimensional Locally Flat Photonic Band
Minho Choi, Christopher Munley, Virat Tara +4
Photonic flatbands offer promising light-matter interaction due to their unique slow-light nature. In recent years, flatbands have also attracted significant interest in optical en…
Meta-optical Miniscope for Multifunctional Imaging
Zhihao Zhou, Khushboo Kumari, Ningzhi Xie +6
Miniaturized microscopes (miniscopes) have opened a new frontier in animal behavior studies, enabling real-time imaging of neuron activity while leaving animals largely unconstrain…
Electrically reconfigurable nonvolatile transmissive metasurface in visible
Virat Tara, Romil Audhkhasi, Andrew Tang +5
The synergy between metasurfaces and non-volatile phase change materials (PCMs) has created many reconfigurable photonic devices for applications in optical memory, optical computi…
Scalable Ion Fluorescence Collection Using a Trap-Integrated Metalens
Hae Lim, Johannes E. Fröch, Christian M. Pluchar +2
A scaled trapped-ion quantum computer will require efficient fluorescence collection across a large area. Here we propose and demonstrate a compact monolithically integrated system…
Singleshot Multispectral Imaging via a Chromatic Metalens Array
Romil Audhkhasi, Ningzhi Xie, Johannes E. Fröch +1
Real time, singleshot multispectral imaging systems are crucial for environment monitoring and biomedical imaging. Most singleshot multispectral imagers rely on complex computation…
