50 meters of optical fiber shrunk to the size of microchips

Long coils of optical waveguides any structure that can guide light, like conventional optical fiber can be used to create a time delay in the transmission of light. Such photonic delays are useful in military application ...

New vacuum power amplifier demonstrated at 0.85 Terahertz

The submillimeter wave, or terahertz, part of the electromagnetic spectrum falls between the frequencies of 0.3 and 3 terahertz, between microwaves and infrared light. Historically, device physics has prevented traditional ...
