Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

Light fields, as a form of electromagnetic waves, are characterized by fundamental parameters including intensity, phase, and polarization. Precise imaging of these three parameters is crucial for ...

A research team from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has advanced the ...

For example, by adding or dropping a particular color, or wavelength, of light traveling in an optical fiber, scientists can control the amount of information carried by the fiber. By altering the ...
