Review discusses using nonlinear optics with structured light

Light can be tailored, much like cloth, weaving and stitching a pattern into the very fabric of light itself. This so-called structured light allows us to access, harness and exploit all light's degrees of freedom, for seeing ...

'Chaotic' way to create insectlike gaits for robots

Researchers in Japan and Italy are embracing chaos and nonlinear physics to create insectlike gaits for tiny robots—complete with a locomotion controller to provide a brain-machine interface.

What really happens at femtosecond junctions?

When beams of ultra-short laser pulses running in the same direction intersect with each other at a noticeable angle, various interactions occur between the pulses. These physical phenomena are complicated, and their mathematical ...

Physicists design a nano-resonator with strong nonlinear response

An international research team has found a way to make frequency conversion of light at the nanoscale 100 times more efficient. The new method is based on isolated dielectric nanoparticles supporting so-called bound states ...
