Plasma Wave Seed for Raman Amplifiers.
It is proposed to replace the traditional counterpropagating laser seed in backward Raman amplifiers with a plasma wave seed. In the linear regime, namely, for a constant pump amplitude, a plasma wave seed may be found by construction that strictly produces the same output pulse as does a counterpropagating laser seed. In the nonlinear regime, or pump-depletion regime, the plasma-wave-initiated...
متن کاملModeling backward-pumped Raman amplifiers
We describe a robust shooting algorithm to model backward-pumped Raman amplifiers. This algorithm uses a continuation method and a Jacobi weight in conjunction with the shooting algorithm. We compare this algorithm to the commonly used relaxation algorithm. We find that the shooting algorithm is more flexible, in that it can be applied to amplifiers in which one fixes the gain, in contrast to t...
متن کاملMulti-Mode Mid-IR Silicon Raman Amplifiers
This paper discusses the prospects of silicon as a Mid-wave Infra-red Raman crystal. As a specific example of novel devices that can be realized, we introduce the concept of multi-mode silicon Raman amplifiers and their application in infrared image pre-amplification. The same technology also has application in incoherent beam combining.
متن کاملSilicon Raman Amplifiers, Lasers, and Their Applications
Silicon Photonics is emerging as an attractive technology in order to realize low cost, high density integrated optical circuits. Realizing active functionalities in Silicon waveguiding structures is being pursued rigorously. In particular, the Stimulated Raman scattering process has attracted considerably attention for achieving on-chip light generation, amplification and wavelength conversion...
متن کاملEnergy Scavenging in Silicon Raman Amplifiers
Continuous-wave Raman amplification in silicon waveguides with negative electrical power dissipation is reported. It is shown that a p-n junction can simultaneously achieve carrier sweep-out leading to net continuous-wave gain, and electrical power generation. The approach is also applicable to silicon Raman lasers and other third-order nonlinear optical devices. 1 Silicon-on-Insulator (SOI) ha...
