Terahertz (THz) waves, situated between the microwave and infrared regions of the electromagnetic spectrum, have drawn ...

Ferroelectric Liquid Crystals (FLCs): A type of liquid crystal that exhibits spontaneous polarization, allowing them to respond to electric fields. Spontaneous Polarization: The electric ...

The team used the method to create a microscopic lens of liquid crystals able to focus light depending on the polarization of light shining through it. First, the team beamed polarized light to ...

Liquid crystal (LC)-based Pacharatnam-Berry phase optical elements (PBOEs) (Fig. 1(a)) are a promising solution, offering an ultrathin form factor, high diffraction efficiency, polarization ...

These designs highlight the versatility of liquid crystals in enhancing the performance of polarization splitters. Moreover, researchers have explored chiral dual-core PCFs to create efficient ...

By using optically active liquid crystals as reaction sites, researchers at University of Tsukuba have successfully achieved ...

The first is a layer of liquid crystals sandwiched between glass plates – similar to a conventional LCD but specially designed to rotate light polarization with high precision. The second component is ...

When the electric field is applied, the orientation of the liquid crystal molecules changes, which in turn alters the polarization of the light passing through them. This light then passes through a ...

After watching [Ben Krasnow]’s efforts to build a liquid crystal display, we can easily see why the suits thought what they did. It’s an amazing engineering feat. Before building his own ...

When patterned as diffractive lenses, LCPGs can provide non-mechanical control over beam divergence and variable focusing. These dynamic elements enable a range of applications, such as machine vision ...

The liquid crystals start out looking like twisted ladders because they orient themselves to microscopic grooves, called "rubbings," in the top and bottom polarization panels (at right angles to ...
