VPIcomponentMakerTM Optical Amplifiers
Highly-advanced optical amplifier models in VPI software incorporate super-stable and efficient algorithms for the most demanding amplifier design tasks including: multi-band, multi-stage, hybrid, Raman, doped-fiber and doped-waveguide amplifiers.
The same models can be used in systems simulations using the same GUI, as they incorporate advanced signal representations including multiple sampled bands, noise-bins and parameterized signals. Alternatively, doped amplifiers (fiber and waveguide) can be automatically characterized and converted into pump-power dependent Black-Box models for rapid systems simulations of gain-controlled amplifiers, so you can design your own control loop with VPI.
Applications
