The quantum theory of damping is presented and illustrated by means of a driven damped harmonic oscillator. The theory is formulated in the coherent state representation which illustrates very vividly ...

Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special ...

This paper presents a single-ended efficient 290 GHz harmonic oscillator, realized using 0.8 μm transferred-substrate (TS) InP-DHBT technology. The architecture of this oscillator is based on a third ...

The synchronous oscillator (SO) and the coherent phase-locked synchronous oscillator (CPSO) are universal multifunctional networks that track, synchronize, and amplify as much as 80 dB; improve SNR by ...
