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…
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…
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…
