We’re not talking WiFi here, but plain optical signals. Free-space optical communication, or FSO, is an interesting and easy way to transmit signals through light beams. Forget expensive lasers ...

Researchers have developed a new type of optical receiver, able to restore chaotic signals in free-space optical communication links distorted by atmospheric turbulence. Using a system of optical ...

This factor, as well as the limited availability of radio frequencies and the requirement for licences for their use, makes the concept of free-space optical communication potentially very ...

Space communication systems are increasingly ... the research team at Chalmers was able to demonstrate a noise-free optical amplifier a few years ago. But until now, the silent amplifier has ...

Researchers from TU/e have transmitted data between the TU/e campus and the High Tech Campus over a 4.6 km distance using ...

Engineers at Duke University have successfully manipulated laser beams to create intricate 3D patterns known as 'optical ...

Knots are generally understood to form due to twists and turns of long, flexible materials that keep shoes on your feet or ...

The light receiver fixes signals in weather, helping send messages in places where networks don’t work, like remote areas. Photo of the photonic chip made. Credit: Politecnico di Milano Researchers ...

In a major tech breakthrough, researchers in Eindhoven have used invisible light to send data wirelessly across the city at ...

Unlike traditional benchtop designs, Edmund Optics’ isolators are integration-ready, making them perfect for embedded systems and production modules. With Edmund Optics’ globally trusted inventory and ...

Originally driven by astronomy, these issues now concern near ground imaging, satellite observation, ground-space and near ground optical free-space telecommunications ... PSF prediction, digital ...
