Abstract: A ray tracing method has been performed to calculate the focus spot size of two-dimensional focusing grating couplers that are produced by holographic interferometry of freely propagating ...

Canada has a new coin and it's meant to recognize the inner strength of Inuit. An Inuk who grew up in Newfoundland and ...

We demonstrate a real-time holographic display using quantum-dot doped liquid crystal with a build-up time of several to tens of milliseconds, and the maximum diffraction efficiency is measured up to ...

Perovskite has emerged as competitive candidates because of their superiority in high refractive index, flexible bandgap tunability, and low-cost preparation. Here, we report giant refractive index ...

This approach is highly versatile, facilitating the fabrication of both transmission- and reflection-type volume holographic grating structures starting from various reaction systems, and the ...

One potential problem with that prediction: the public has to want to replace physical objects with holographic versions.So far, Apple’s experience with Apple Vision Pro does not imply that the ...

A reel showing chocolate bars with a unique colourful glint on their surface has gone viral on Instagram. Many foodies were fascinated by how it's made.
