Photonic Origami of Silica on a Silicon Chip with Microresonators and Concave Mirrors
Manya Malhotra, Ronen Ben-Daniel, Fan Cheng +1
3D printing of high-quality silica photonic structures is particularly challenging, as surface roughness at the nanoscale can severely degrade optical performance through scatterin…

Solving the inverse problem for the design of omnidirectional lenses with an ultimately high numerical aperture
Shay Rabani, Kirill Shvalb, Boris Malomed +1
We introduce a new type of lens that focuses a plane wave into a spherical one, where light comes from all directions. Our method also suggests the design of ideal optical tweezers…
