Metasurface Freeform Nanophotonics
Alan Zhan, Shane Colburn, Christopher M. Dodson +1
Freeform optics aims to expand the toolkit of optical elements by allowing for more complex phase geometries beyond rotational symmetry. Complex, asymmetric curvatures are employed…

Tunable metasurfaces via subwavelength phase shifters with uniform amplitude
Shane Colburn, Alan Zhan, Arka Majumdar
Metasurfaces with tunable spatial phase functions could benefit numerous applications. Currently, most approaches to tuning rely on mechanical stretching which cannot control phase…
