Wafer-scale conformal metasurface optics

Curved and conformal optics provide additional geometric degrees of freedom that enable enhanced optical performance while satisfying non-optical constraints such as ergonomics, aerodynamics, and wearability. However, existing fabrication approaches for curved metasurfaces are li...

Limits and Trade-Offs of Shift-Invariant Meta-Optical Encoders for Image Compression

Meta-optical encoders can reduce image data before electronic readout or transmission, but engineered point-spread functions (PSFs) do not automatically outperform conventional imaging. We study scene-agnostic, shift-invariant, linear optical encoders using both a fixed total-var...
