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.

Mott insulators, governed by strong correlations, exhibit exceptional nonlinear optics. Guided by first-principles, ...

Harvard researchers have found that silica, long thought to lack the right properties for optical metasurfaces, can sometimes ...

Capasso himelf called the discovery “a counterintuitive breakthrough in nanotechnology.” He added, “We have demonstrated in ...

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.

Optical isolation and nonreciprocal devices are pivotal components in modern photonic systems, ensuring unidirectional light propagation and safeguarding sensitive equipment from unwanted reflections.

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

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 ...

Paper-thin optical lenses simple enough to mass produce like microchips could enable a new generation of compact optical devices. Researchers have fabricated and tested flat lenses called Fresnel zone ...

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 ...
