orbital angular momentum News
Mathematical Approach Deciphers Orbital Angular Momentum Information
GUANGZHOU, China, Aug. 14, 2023 — Researchers from Sun Yat-sen University and École Polytechnique Fédérale de Lausanne (EPFL) have made progress in the use of interferometry to decipher orbital angular momentum (OAM) spectrum information. Lightwaves with OAM have become important in technologies including communication, imaging, and quantum information processing. For these to be effective, it’s crucial to know the exact structure of these helical light beams. So far, this has proven difficult.
'Edge-First Flying Doughnut' Rewrites Rules on Angular Momentum
COLLEGE PARK, Md., May 19, 2021 — Researchers at the University of Maryland have shown that photons in a vacuum can have orbital angular momentum (OAM) vectors that point sideways, at 90° to the direction of propagation. The discovery relies on a spatiotemporal optical vortex...
Researchers Structure Light with Two Independent Orbital Angular Momenta
LOS ANGELES, Aug. 26, 2020 — Researchers at the University of Southern California (USC) combined twisted light and optical frequency combs to produce a new, dynamic light structure. The Optical Communications Lab at USC had been researching twisted light beams and frequency...
Quantum Secret Sharing Uses Structured Light to Achieve High-Dimensional States
JOHANNESBURG, Aug. 10, 2020 — Researchers at the University of the Witwatersrand (Wits) demonstrated an 11-dimensional quantum state and used it to share sensitive information securely from one sender to 10 parties. They used structured light to achieve a high-dimensional...
Supertwisted Light from a Metasurface Laser
Jun 29, 2020 — Structured light refers to the tailoring or shaping of light in all its degrees of freedom. The recent development of structured light supports applications such as optical communications, enhanced resolution in imaging, and optical trapping and...
Multidimensional Quantum Communications with Legacy Fibers
JOHANNESBURG, Jan. 28, 2020 — In a new “twist” on quantum communication using optical fiber, researchers from the University of Witwatersrand (Wits) and Huazhong University of Science and Technology (HUST) have demonstrated that multiple quantum patterns of twisted...
Way to Generate OAM Pulses in UV Range Could Help in Materials Research
MOSCOW, Jan. 27, 2020 — Scientists from the Skolkovo Institute of Science and Technology (Skoltech), in collaboration with researchers from the Shanghai Institute of Optics and Fine Mechanics and the Helmholtz Institute, have proposed a way to generate intense, short,...
Special Majorana-Like Vector Photon Beams
Jan 6, 2020 — A special, newly proposed photon called a “Majorana-like” photon possesses spin angular momentum (SAM) and orbit angular momentum (OAM) coupled together. Experiments with mouse brain tissue have revealed the plausibility of using these...
Commemorating 30 Years of Optical Vortices
CHANGCHUN, China, Nov. 6, 2019 — Thirty years ago, Pierre Coullet et al. proposed that a special optical field exists in laser cavities bearing some similarity with the superfluid vortex. This observation was the first indicator that optical vortices could exist. Since then,...
Understanding the Flow of Angular Momentum for Improved Data Storage
BERLIN, May 3, 2019 — A team led by scientists at Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) sought to better understand the flow of angular momentum during ultrafast optical demagnetization in a ferromagnetic material. Working with...
Optical Vortexes Could Help Meet Network Traffic Demands of Tomorrow
TOKYO, March 14, 2019 — A multiplexer/demultiplexer module based on an optical vortex, built by scientists at Tokyo Institute of Technology, could be used to strengthen optical networks so they can meet increasingly heavy traffic demands. The team developed an...
Microgears Made from Germanium Generate Twisted Light
SOUTHAMPTON, England, Dec. 31, 2018 — Miniature gears made from germanium have demonstrated the ability to generate light that has orbital angular momentum. This new light source could be used to boost the amount of data that can be transmitted through optical computing. Light carries...
Complex States of Light Generated via Metasurface
CAMBRIDGE, Mass., Nov. 7, 2017 — Researchers have designed a method for converting arbitrary spin angular momentum (SAM) states of light into total angular momentum states. This method is characterized by the superposition of independent orbital angular momentum (OAM), and could...
Quantum Cloning Machine Could Prevent Hacking
OTTAWA, Ontario, Feb. 7, 2017 — Universal optimal quantum cloning of high-dimensional photonic states has been achieved using the symmetrization method. The work has led to the discovery of information that could help system administrators protect quantum computing networks from...
Vortex Laser May Help Shape the Future of Data Transfer
BUFFALO, N.Y., Sept. 6, 2016 — A light-based communications tool that is structured to carry data in a helical path may enable fast transfer of large amounts of data, resolving potential bottlenecks in data transfer as the demand for information sharing grows. The novel technique...
Angular Acceleration Observed in Helical Light Beams
JOHANNESBURG, April 23, 2015 — The orbital angular momentum of laser light traveling along a helical path through space can accelerate and decelerate as it spins into the distance. This is the first time that angular acceleration has been observed with light, according to...
Fiber design could boost Internet bandwidth
BOSTON – A new kind of optical fiber stable enough to transmit donut-shaped laser beams called optical vortices, or orbital angular momentum (OAM) beams, promises to increase bandwidth dramatically to meet today’s ever-increasing demand for...
New Optical Fiber Puts a Twist on Data Transmission
LOS ANGELES and BOSTON, June 28, 2013 — The data capacity of single-mode optical fibers, while having increased by four orders of magnitude over the last 30 years, is rapidly reaching the limits imposed by the fiber’s nonlinear effects. But a bicoastal team has devised a new fiber optic...
Optical Vortex Beams Emit on Silicon
BRISTOL, England, Oct. 18, 2012 — The smallest emitter of orbital angular momentum (OAM) light — light that travels in a twisting, corkscrew-like manner — was created on silicon. The chip is one thousand times smaller than any other such device reported to date and could be used in...
Nano light mill motor controlled by wavelength changes
BERKELEY, Calif. – A newly developed light mill could lead to a whole new crop of nanoscale devices, including nanoscale solar light harvesters, nanoelectromechanical systems, and nanobots that could manipulate DNA and other biological molecules in vivo. ...
'Tornadoes' Transferred From Light to Sodium Atoms
GAITHERSBURG, Md., Nov. 10, 2006 -- For the first time, tornado-like rotational motions have been transferred from laser light to atoms in a controlled way. The new quantum physics technique can be used to manipulate a state of matter called Bose-Einstein condensate (BEC) and possibly...
