Phase-change metasurfaces integrate subwavelength optical architectures with materials whose refractive index and absorption can be dynamically and reversibly altered through an external stimulus, ...

Liquid-crystal (LC) phase modulators are widely used in optical systems because of their advantages of low power consumption, lightweight, flexible bandwidth adjustment, and non-mechanical movements.

The design strategy for terahertz metasurfaces capable of achieving spin-selective functionality through complex-amplitude modulation is systematically categorized into four distinct parametric ...

Metalens is a kind of optical metasurface composed of metaatoms for manipulating incoming light's amplitude, phase, and polarization. Unlike traditional refractive lenses, metalens can modulate the ...

(a) The process for fabricating LC phase modulator with the MMOT structure. (b) The schematic of LC phase modulator with MMOT structure. Liquid-crystal (LC) phase modulators are widely used in optical ...
