Free-space optical (FSO) communication systems utilise light to wirelessly transmit data through the atmosphere. Such systems offer the potential for extremely high data rates, addressing the growing ...

These devices are the first to demonstrate simultaneous control of all four optical degrees of freedom, namely, amplitude, phase, polarization ellipticity, and polarization orientation--a world record ...

The 5.4 km free-space quantum communication link between the University of Ottawa and the National Research Council Canada, where real-time atmospheric turbulence measurements were conducted to train ...

With photonic integrated circuits, above all silicon photonics, seeing a wave of industry hype owing to their vast potential in the datacom and telecom applications, relevant suppliers in Taiwan's ...

While the fiber-optic backbone is already widely installed, only 5 percent of commercial buildings in the United States have fiber to their door, even though most are within a mile of a fiber-optic ...

Researchers at Columbia Engineering have developed a new class of integrated photonic devices—"leaky-wave metasurfaces"—that can convert light initially confined in an optical waveguide to an ...
