In principle, optical phase-sensitive amplifiers are known to be capable of realizing noiseless amplification, as well as improving the signal-to-noise-ratio of optical links by 3 dB compared to ...

Close up of an optical amplifier chip, similar to the one detailed in this study, that is being developed in the lab of Stanford physicist Amir Safavi-Naeini. A red laser light shines from an optical ...

The amplifier developed by Chalmers researchers is compact, measuring just a few centimeters, yet it can process ten times larger amounts of data per second than current optical communication systems.

The continually increasing data traffic across the globe is placing greater demands on the capacity of communication systems. A research team from Chalmers University of Technology, in Sweden, has ...
