Anti-resonant hollow-core optical fiber reduces 'noise'

A new hollow optical fiber greatly reduces the "noise" interfering with the signals it transmits compared to the single-mode fibers now widely used, researchers at the University of Rochester report.

Lighting the way to infrared detection

EPFL physicists propose a new path to detect infrared radiation with outstanding sensitivity, allowing detection of signals as low as that of a single quantum of light.

Quantum light squeezes the noise out of microscopy signals

Researchers at the Department of Energy's Oak Ridge National Laboratory used quantum optics to advance state-of-the-art microscopy and illuminate a path to detecting material properties with greater sensitivity than is possible ...

Multidimensional, dual-channel vortex beam generator

Optical vortices, characterized by a helical phase front and doughnut-shaped intensity distribution, contribute to a broad range of applications, from microscopy to optical communications. And applications for optical vortices ...

Quantum exciton found in magnetic van der Waals material

Things can always be done faster, but can anything beat light? Computing with light instead of electricity is seen as a breakthrough to boost computer speeds. Transistors, the building blocks of data circuits, are required ...
