Engineering Shadows to Fabricate Optical Metasurfaces

Engineering shadows to fabricate optical metasurfaces.

Optical metasurfaces-patterned arrays of plasmonic nanoantennas that enable the precise manipulation of light-matter interactions-are emerging as critical components in many nanophotonic materials, including planar metamaterials, chemical and biological sensors, and photovoltaics. The development of these materials has been slowed by the difficulty of efficiently fabricating patterns with the r...

Optical metasurfaces: from planar to conformable optics

Abrupt modifications of the fields across an interface can be engineered by depositing an array of subwavelength resonators specifically tailored to address local amplitude, phase and polarization changes [1]. Physically, ultrathin nanostructure arrays, called “metasurfaces”, control light by engineering artificial boundary conditions of Maxwell’s equations. Metasurfaces have been implemented t...

Optical metasurfaces for polarization-controlled beam shaping.

We have developed multifunctional optical beam shapers based on plasmonic metasurfaces. The metasurfaces are composed of subwavelength-spaced polarization- and wavelength-selective optical nanoantennas that allow encoding several beam shapers on a single element. We demonstrate numerically and experimentally beam shapers that can be used to switch between arbitrary beam shapes. We specifically ...
