Low-loss Metasurface Optics For Deep UV

NIST Inventors
Henri Lezec and Wenqi Zhu
High-performance optical-metasurface-based components configured to at frequencies of UV light and, in particular, in deep UV range and performing multiple optical-wavefront-shaping functions (among which there are high-numerical-aperture lensing, accelerating beam generation, and hologram

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

NIST Inventors
Henri Lezec and Wenqi Zhu
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

High-Performance Ultaviolet Optical Elements Based On Metasurface Technology

NIST Inventors
Henri Lezec , Wenqi Zhu and Jessie Zhang
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
