Metasurfaces, also referred to as liquid crystal meta-surfaces, are a type of manufactured materials that uniquely manipulate light.
They consist of a thin layer of liquid crystals that have been patterned with nano- or subwavelength features that are intended to control the amplitude, phase, and polarisation of light at the surface.
Metasurfaces function on a far thinner scale and provide unheard-of control over the characteristics of light, in contrast to conventional optical components like lenses or mirrors, which depend on bulk materials and intricate three-dimensional structures.
Due to their capacity to control light at the nanoscale, which enables a variety of applications in optics and photonics, they have attracted a lot of attention recently.These meta-surfaces’ liquid crystals are made of materials whose properties fall in between those of regular liquids and those of solid crystals.
They can react to outside stimuli like electric fields or temperature changes because they have long-range molecular order.
The liquid crystal molecules’ orientation can be accurately changed by implementing the proper control mechanisms, producing customised optical responses.
Liquid crystal meta-surfaces have subwavelength features on its surface that are specifically designed to interact with incident light waves.
The behaviour of the transmitted, reflected, or dispersed light is determined by the positioning and geometry of these structures.
Researchers have found that they can precisely regulate the characteristics of light, such as its direction, polarisation, and wavelength, by carefully engineering the shape, size, and orientation of the nanostructures.There are numerous uses for liquid crystal meta-surfaces in optics and photonics.
In place of heavy lenses or intricate optical systems, they can be employed to make flat optical elements.
These components, among other things, have the ability to focus light, direct beams, produce holographic images, and change the polarisation of light.
Applications for liquid crystal meta-surfaces include displays, sensing, and imaging.
The global liquid crystal meta-surfaces market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
LiDAR developed by Lumotive using its Crystal Metasurfaces and CMOS fabrication is claimed to be a “industry first.“
A reflective 1D dynamic metasurface based on liquid-crystal tuning of resonant subwavelength elements has just been created by Lumotive.
