NTT’s research division has developed what it claims to be the world’s first programmable nonlinear photonic waveguide capable of switching between multiple nonlinear-optical functions on a single ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called skyrmions. These light vortices hold their shape even when disturbed, making them ...

Scientists have built a soft, wireless Implant that lets the brain interpret patterned light as if it were a new kind of touch, turning beams into information the cortex can actually use. Instead of ...
