Reliably tracking and manipulating the mammalian nervous system in laboratory or clinical settings allows neuroscientists to test their hypotheses, which may in turn lead to new important discoveries.

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called ...

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 ...

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.

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 ...

Caltech scientists have developed a way to guide light on silicon wafers with low signal loss approaching that of optical ...

A tiny optical device built into a silicon chip has achieved the slowest light propagation on a chip to date, reducing the speed of light by a factor of 1,200 in a study reported in Nature Photonics ...

Light does a lot of work in the modern world, enabling all types of information technology, from TVs to satellites to ...

It may seem at times that there is a divide between the optical/photonic domain and the RF one, with the terahertz zone between them as a demarcation. If you need to make a transition between the ...
