Laser diodes are semiconductors that generate light and amplify it using repeated reflection or ‘optical feedback’. Once the light has achieved desirable optical gain, laser diodes release it as ...

The introduction of topology in photonic systems has attracted considerable attention not only for the elaborate molding of light but also for its practical applications in novel photonic devices.

(Nanowerk News) The light control performance of photonic crystals is closely related to their lattice constant, which typically requires the lattice constant to be in the same order of magnitude as ...

(Nanowerk Spotlight) Van der Waals (vdW) integration refers to a physical assembly strategy that was originally applied in the two-dimensional (2D) materials and nanotechnology community to construct ...

Researchers have developed a way to create photonic time crystals and shown that these bizarre, artificial materials amplify the light that shines on them. These findings could lead to more efficient ...

A team of researchers designed a two-dimensional photonic time crystal that they say could have applications in technologies like transmitters and lasers. Despite their name, photonic time crystals ...

In a recent study published in Science Advances, a team of researchers have created a new method of making photonic time crystals, which is a type of artificial material capable of amplifying the ...

Researchers have developed a way to create photonic time crystals, and they have shown that these bizarre, artificial materials amplify the light that shines on them. These findings, described in a ...

A team of researchers has developed a novel method for using cholesteric liquid crystals in optical microcavities. The platform created by the researchers enables the formation and dynamic tuning of ...
