Modern communication networks require amplified optical signals to cover long distances without losing information. Common ...

Researchers from EPFL and IBM have developed a groundbreaking photonic-chip-based traveling-wave parametric amplifier (TWPA) ...

The researchers' communication system uses an optical amplifier in the receiver that amplifies the signal with the least possible noise so that its information can be recycled. Just like the glow ...

Using gallium phosphide-on-silicon dioxide technology, thecompact photonic chip boosts signals with unprecedented efficiency.

Unlike regenerators, which have to convert light to electricity in order to amplify it and then convert it back again to light, the optical amplifier amplifies the light signal itself. Developed ...

But just like a weak radio signal, these optical signals need to be amplified to travel long distances without losing information. The most common amplifiers, erbium-doped fiber amplifiers (EDFAs), ...

The brand, best known for its affordable high-resolution music streamers, has released its first amplifier for traditional hi ...

These repeaters worked by receiving the weakened optical signals with photodiodes, demodulating the signal before running it through semiconductor amplifiers, and converting it back into light ...

Assuming that Rega is able to keep the Brio MK7 under $1,000 (or damn near close to it), the British amplifier is going to be ...

EPFL researchers have experimentally observed both first- and second-order dissipative phase transitions (DPTs) in a ...
