Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase ...
Photonics researchers have demonstrated how self-imaging of light, a phenomenon known for nearly two centuries, can be applied to cylindrical systems, facilitating unprecedented control of light's ...

Study confirms "dark points" in light waves can move faster than light
Physicists have directly tracked tiny points of darkness in laser light racing faster than light itself, without breaking Einstein’s rules. The new measurements show that these “dark points” in a ...
This Collection supports and amplifies research related to SDG 9 - Industry, Innovation and Infrastructure. The ability to control the phase, polarization, and intensity of light is extensively ...
Researchers from Wits University and Universitat Autònoma de Barcelona show how controlling the structure of photons in space and time enables tailored quantum states for next-generation communication ...
Researchers used structured light and switchable fluorescent molecules to reduce the background light from the out-of-plane regions of microscope samples. This method allowed for the acquisition of ...
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 ...
Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field ...
Light doesn’t just travel in straight lines—it can also twist. And when it does, it opens new frontiers in science and medicine. A recent breakthrough led by Professor Igor Meglinski at Aston ...
(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 ...
After futzing around with a cheap pico projector, a webcam and a little bit of software, [Jas Strong] built herself a 3d scanner. In spite of the dozens of Kinect-based scanner projects, we’ve seen ...
