Measuring blood flow in the brain is critical for responding to a range of neurological problems, including stroke, traumatic ...

This is the first time the novel imaging technique has been applied to telescopes. For the first time, astronomers have ...

Lithium niobate has emerged as a cornerstone material in advanced photonic technologies, owing to its exceptional electro‐optic coefficients, wide optical transparency and strong nonlinear properties.

Kerry Vahala and collaborators from UC Santa Barbara have found a unique solution to an optics problem. When we last checked in with Caltech's Kerry Vahala three years ago, his lab had recently ...

Researchers have harnessed nonlocal artificial materials to create optical systems that emulate parallel spaces, wormholes, ...

Researchers armed with a new "photonic lantern" device have discovered an unexpectedly asymmetrical disk of gas swirling ...

A new "lensless" device could help, as it uses light to instantly detect harmful microorganisms. Usually, in order to check drinking water for bacteria, a sample of that water must be cultured in a ...

Non-invasive device worn on the forehead uses laser technology and an array of detectors, and could form the basis of methods for monitoring brain blood flow.

In the realm of general relativity, black holes are well-known for their ability to trap light and matter by bending spacetime, creating a point of no return. While black holes have fascinated ...

Andrew Weiner and Daniel Leaird found a way to put a single pulse of light into an arrayed wave guide grating and get a rapid-fire burst of 21 light pulses out of it, with each pulse separated by only ...
