Cascaded Raman Amplifier

1. VPIcomponentMaker™ Optical Amplifiers encapsulates sophisticated algorithms for solving bidirectional signal, pump and noise propagation in Raman amplifiers.
2. Flexible Raman gain coefficient descriptions allow the pump-wavelength dependence of Raman gain to be described accurately over wide frequency ranges.
3. This example shows the simulation of a cascaded Raman amplifier, where a high-power pump is first converted to an intermediate frequency before amplifying the signals.
4. Many other schemes can be investigated as there is full interaction between pump, signal and noise photons, and also doped fiber and Raman amplifiers can be combined for pump-reuse designs.
