A tunable metasurface can control optical light in space and time, offering a path toward new ways of wirelessly and securely transmitting large amounts of data both on Earth and in space. It is a ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called skyrmions. These light vortices hold their shape even when disturbed, making them ...

Researchers have harnessed nonlocal artificial materials to create optical systems that emulate parallel spaces, wormholes, and multiple realities. A single material acts as two distinct optical media ...

Researchers have developed, for the first time in the world, incoherent dielectric tensor tomography (iDTT), a technology ...

Phostech has more than 15 years of experience designing optical & lighting systems such as LED lighting, backlights, picoprojectors, testing systems, optical films (diffractive & holographic), optical ...

Optical cavities, also known as optical resonators, are structures that confine light within a small volume by utilizing highly reflective surfaces. These cavities allow light to circulate or bounce ...
