Nonlinear optics is the study of how intense light interacts with matter. The optical response of a material usually scales linearly with the amplitude of the electric field. At high powers, however, ...

Light is traditionally described by properties such as wavelength, amplitude, phase and polarization. Advances in optics have ...

Conjugated polymers have long promised a cheap, flexible route to photonic devices that inorganic crystals can only match at far greater cost and complexity. Now a team of researchers from the ...

A tiny device that can be reprogrammed using a laser could lead to adaptable devices for computing, imaging and ...

Optical skyrmions have been demonstrated across many wavelengths, but so far only one at a time for a monochrome color palette. Now they are reported as broadband topologies across the entire visible ...

A recent study has unveiled a transformative nonlinear optical metasurface technology. This new technology, characterized by structures smaller than the wavelength of light, paves the way for ...

Nonlinear optical crystals are a class of materials that exhibit unique properties when interacting with light. Unlike conventional optical materials, which respond linearly to the electric field of ...

Molybdenum disulfide, the layered semiconductor second only to graphene in popularity among two-dimensional materials, has ...

Nanostructured device efficiently transforms light into different frequencies – including those at technologically important ...

Engineers at the University of Wisconsin–Madison have designed a new type of quantum nanostructure that could enable optical ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS The ability to dynamically control the nonlinear phase in optical systems is crucial. It improves flexibility, ...

In the 1960s, physicists showed how light could interact with itself in intriguing ways thanks to a process known as second-harmonic generation. In the right kind of material, two photons of a certain ...
