In the realm of general relativity, black holes are well-known for their ability to trap light and matter by bending ...

A team of researchers has engineered a groundbreaking optical device that mimics the physics of black holes and their ...

Offers new possibilities to control light across the spectrum and insight into light–matter interactions. The device, reported in Advanced Photonics, functions as an optical black hole or optical ...

Knots are generally understood to form due to twists and turns of long, flexible materials that keep shoes on your feet or ...

Twisted moiré photonic crystals—an advanced type of optical metamaterial—have shown enormous potential in the race to ...

Just over 400 years ago, Hans Lipperhey filed a patent for an optical device that he (and possibly other Dutch spectacle makers) had invented by putting together a converging and a diverging lens ...

In this online engineering specialization, you will deepen and apply your knowledge of optical devices to design electronics that adapt to different optical environments. You will complete courses in ...

"Optical modulators are devices that help generate high-speed signals from optical fibers. They can convert or change things ...

Even more speculatively, we can imagine optical transistors that operate with single photons, and demonstrations of possible schemes of operation have already been made 12. Such devices could ...

In the realm of general relativity, black holes are well-known for their ability to trap light and matter by bending ...

In twisted moiré photonic crystals, how the layers twist and overlap can change how the material interact with light. By changing the twist angle and the spacing between layers, these materials can be ...
