Low-loss Metasurface Optics For Deep UV

NIST Inventors
Henri Lezec , Wenqi Zhu and Shawn Divitt
In this invention, we employ a novel approach to construct high-performance optical elements operating in the UV and deep-UV regime. Our technology is based on metasurfaces, where we design nanoantennas with sizes a fraction of the scale of the wavelength of UV light and arrange them over a planar

High-Performance Ultaviolet Optical Elements Based On Metasurface Technology

NIST Inventors
Henri Lezec , Wenqi Zhu and Shawn Divitt
Shrinking conventional optical systems to chip-scale dimensions will benefit custom applications in imaging, displaying, sensing, spectroscopy, and metrology. Towards this goal, metasurfaces — planar arrays of subwavelength electromagnetic structures that collectively mimic the functionality of

Metasurface Optical Pulse Shaper for Shaping an Optical Pulse in a Temporal Domain

NIST Inventors
Henri Lezec , Wenqi Zhu and Shawn Divitt
A metasurface optical pulse shaper includes a metasurface with superpixels disposed on an entry side of the metasurface and a wire grid polarizer disposed on an exit surface of the metasurface for controlling a phase, amplitude, or polarization of an optical pulse, wherein the metasurface in
