‘Acceleration beats’ shine bright light on a novel universal modulation regime in a semiconductor-based laser
(Left) A lighthouse with the green-color lamp that rotates with angular frequency ω. (Right) It’s spectrum for increasing rotation frequency, showing spectral wiggles close to the two Doppler-shifted peaks—the acceleration…
Scientists crack new method for high-capacity, secure quantum communication
