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 ...

Researchers have developed a novel “Janus meta-imager” that uses diffractive neural networks to asymmetrically transmit and ...

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 ...

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.

Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns.

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

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 ...
