By using paired, offset optical combs and RF electronics, researchers devised a unique atomic-clock architecture.

Abstract: This article describes the design of an IQ impedance modulator radio front-end which is used to generate long range (LoRa) symbols with backscattering techniques, allowing building low-power ...

Abstract: The design, fabrication and characterization of a traveling wave Ti:LiNbO/sub 3/ Mach-Zehnder interferometric modulator are discussed. The dependence of the velocity match condition on ...

A new method in Nature Photonics uses electrochemical fluorescence modulation to separate overlapping signals in multicolor ...
