Spatio-temporal isolator in lithium niobate on insulator

Integrated photonics is making strides towards hosting an increasing range of functionalities on a chip. Examples include information processing and computation as well as optical sensing and ranging applications. This has ...

Using physics to improve root canal efficiency

Scientists used computational fluid dynamics to determine the effect of temperature on root canal cleaning efficiency. Higher temperatures can, to a point, improve cleansing, but this benefit falls off if the temperature ...

A dash of gold improves microlasers

Gold. The word brings to mind wedding rings, buried treasure and California in the 1840's. But when gold is reduced to 1/100,000 the size of a human hair, it takes on an entirely new personality.
