Metasurface Photodetectors [PDF]
Micromachines, 2021 Photodetectors are the essential building blocks of a wide range of optical systems. Typical photodetectors only convert the intensity of light electrical output signals, leaving other electromagnetic parameters, such as the frequencies, phases, and polarization states unresolved.

Electromagnetic Metasurfaces and Reconfigurable Metasurfaces: A Review [PDF]
Frontiers in Physics, 2021 Metamaterial is a kind of material/structure that is artificially designed and has exceptional electromagnetic properties and/or other physical properties, not found in nature. A class of electromagnetic metamaterial with only one or a few layers of periodic or aperiodic arranged cell structures in the direction of electromagnetic waves propagation can

Dynamic Hybrid Metasurfaces [PDF]
Nano Letters, 2021 Efficient hybrid plasmonic-photonic metasurfaces that simultaneously take advantage of the potential of both pure metallic and all-dielectric nanoantennas are identified as an emerging technology in flat optics. Nevertheless, post-fabrication tunable hybrid metasurfaces are still elusive. Here, we present a reconfigurable hybrid metasurface platform by

A True Metasurface Antenna [PDF]
2016 IEEE International Symposium on Antennas and Propagation (APSURSI), 2016 AbstractWe present a true metasurface antenna based on electrically-small resonators. The resonators are placed on a flat surface and connected to one feed point using corporate feed. Unlike conventional array antennas where the distance between adjacent antennas is half wavelength to reduce mutual coupling between adjacent antennas, here the distance ...

Neuromorphic metasurface [PDF]
Photonics Research, 2019 Metasurfaces have been used to realize optical functions such as focusing and beam steering. They use subwavelength nanostructures to control the local amplitude and phase of light. Here we show that such control could also enable a new function of artificial neural inference.

Temperature invariant metasurfaces
High Contrast Metastructures XII, 2023 Abstract Thermal effects are well known to influence the electronic and optical properties of materials through several physical mechanisms and are the basis for various optoelectronic devices. The thermo-optic (TO) effect, the refractive index variation with temperature (dn/dT), is one of the most common mechanisms used for tunable ...
