Bandwidth variable transmitter (BVT) is one of the key enabling technologies for future EONs. In the University of Bristol's lab, transmitters are designed to generate optical signals with variable ...

In the new communication system from researchers at Chalmers University of Technology, in Sweden, a weak optical signal (red) from the spacecraft's transmitter can be amplified noise-free when it ...

Silent amplifier with simplified transmitter improves communication The researchers' communication system uses an optical amplifier in the receiver that amplifies the signal with the least ...

Optical parametric oscillators simultaneously generate two beams of coherent light that are widely tunable in wavelength. This flexibility makes them a popular tool in various areas of scientific ...

NASA lost contact with the interstellar Voyager 1 spacecraft for nearly a week after a technical glitch shut off the probe's main transmitter. Using Voyager's weaker backup transmitter ...

Optical illusions reveal hidden personality traits based on what a person sees first. If one sees mountains, they are friendly and peace-loving. Seeing a dog indicates emotional sensitivity and ...
