An ultra-broadband photonic-chip-based parametric amplifier

Nature
Optical amplification, crucial for modern communication, primarily relies on erbium-doped fibre amplifiers (EDFAs)1,2. Yet, EDFAs only cover a portion of the low-loss spectrum of optical fibres.

A TCAD Approach to Design a Broadband Power Amplifier

, 2010
Technology Computer Aided Design (TCAD) provides an alternate method to study the power amplifier (PA) design prior to fabrication. It is very useful for the extraction of an accurate large signal model.

High power broadband CARM amplifier

, 2016
The simulation of an efficient, broadband cyclotron autoresonance maser (CARM) amplifier operating at a 4MW output power level is presented and discussed. The amplifier is based on a high current accelerator capable of generating a ∼35A pencil electron beam at an accelerating voltage of 450kV.
