In the underwater world, sound is the primary means of communication, as light quickly fades. A Korean research team has ...

Temporal cavity solitons are packets of light persisting in a continuously driven nonlinear resonator. They are robust attracting states, readily excited through a phase-insensitive and ...

Cavities are one of the most common forms of tooth decay among children in the United States. They affect roughly 20 percent of children between the ages of 5 and 11. Multiple factors can influence ...

GaN-based vertical-cavity surface-emitting lasers (VCSELs) are promising for displays, sensing and optical communication, but improving efficiency remains challenging. Researchers have now shown that ...

A cavity is a hole in the tooth. Signs of a cavity include spots or holes on the surface of the tooth and pain sensitivity in the area. Cavities are a symptom of tooth decay. They develop when ...

Scientists at NPL have demonstrated the best-reported laser frequency stability achieved with an optical reference cavity operating at room temperature, marking a major advance in ultrastable laser ...
