Physicists are rethinking time itself. Long treated as a basic part of the universe, time may instead be an illusion—a side ...

In this paper, we propose a novel design of GaN-based planar Gunn oscillator as terahertz signal source. The oscillator has multiple gates and each gate can be individually biased. By controlling gate ...

In this article, we propose a voltage-controlled oscillator (VCO) with a single three-coil transformer, featuring a common-mode (CM) resonance expansion and intrinsic differential 2nd harmonic output.

The Mamyshev oscillator (MO) is a type of fiber laser capable of producing high-energy laser pulses at a tunable repetition rate. It is a mode-locked laser which uses light traveling within a ...
