World's first laser radio transmitter/receiver paves way for ultra-high-speed Wi-Fi. New technology uses lasers to generate radio signals. Romas_ph/Depositphotos. View 2 Images 1 / 2.

My first thought was to modulate a generic 650nm laser diode at a comparatively high frequency and make it a pulse-modulated laser transmitter. Also, employ a suitable laser receiver (capable of ...

Now, researchers have created a system that, with a silent amplifier and record-sensitive receiver, ... a conventional laser transmitter with one wave can now be used to implement the amplifier.

The deep-space optical communication link could revolutionize how scientists communicate with spacecraft as they explore the ...

The demonstration system consists of a flight laser transceiver, a ground laser transmitter and a ground laser receiver. The downlink transmitter has been installed on the Psyche spacecraft, which ...

This system consists out of a ground-based laser transmitter and receiver along with a space-based laser transceiver, which for this experiment was positioned at a distance of 31 million ...

Ericsson’s engineers installed the Ericsson Streetmacro 6701 base station and PowerLight’s laser light receiver station onto a 22-foot-tall pole in a parking lot, about 400 feet from the ...

The United States’ Defense Advanced Research Projects Agency (DARPA) recently achieved a new record in transmitting energy over distance. In tests performed in New Mexico, the Persistent Optical ...

The experiment – witnessed by a group of attendees who could not actually perceive the multi-kilowatt infrared beam – comprises two 4m (13ft)-high towers, a 2kW laser transmitter, a receiver featuring ...

Our simplification of the transmitter means that already existing optical transmitters on board satellites and probes could be used together with the noise-free amplifier in a receiver on Earth ...
