In free-space optical communication scenarios, atmospheric turbulence distorts the complex wavefront of signal-carrying light beams, leading to bit errors and even communication interruptions. Note ...

Structured light can significantly enhance information capacity, due to its coupling of spatial dimensions and multiple degrees of freedom. In recent years, the combination of structured light ...

(Nanowerk News) Researchers have developed a tiny, room-temperature device that creates a special type of structured light called radially polarized photons, which are highly useful for secure ...

Seeing both wide and clear is a fundamental challenge. This is akin to taking a group photo with a smartphone: you want to fit everyone into the frame while also ensuring every face is clearly visible ...
