It will also serve as a general useful introductory guide to all newcomers to the field of liquid crystals and contemporary optics and photonics materials and devices. Studies of liquid crystals are ...

GaAs-based two-dimensional photonic-crystal slab waveguides and InAs quantum dots. This device was said to be the key optical logic device in a future advanced ultrafast-photonics network.

An international research team has for the first time designed realistic photonic time crystals – materials that exponentially amplify light. The achievement offers several possibilities across fields ...

“This work could lead to the first experimental realization of photonic time crystals, propelling them into practical applications and potentially transforming industries," says Professor Viktar ...

In practice this means that a photonic crystal acts like a mirror for waves that have frequencies within the band gap; in fact, dielectric mirrors (alternating slabs of contrasting dielectrics) are ...

One potential application for photonic time crystals is in nanosensing. Asadchy added, “Imagine we want to detect the ...
