VPIcomponentMaker Optical Amplifiers
VPIcomponentMaker Optical Amplifiers is an integrated design environment for doped-fiber and doped-waveguide based amplifier and laser applications, as well as Raman amplifiers.
It offers means to define, test and optimize the gain, noise and efficiency of doped-fiber amplifiers and lasers over wide wavelength ranges, using time-averaged optical signal and noise representations. Time-dynamic and systems simulations can be performed in conjunction with VPItransmissionMaker Optical Systems. Alternatively, amplifier designs can be automatically characterized and converted into pump-power dependent Black-Box models for rapid systems simulations of gain-controlled amplifiers.
The graphical interface allows almost any amplifier topology to be defined from a wide range of waveguides, doped and passive fibers, passive and active components. Interactive simulations, including multi-dimensional sweeps, optimizations and dynamical variations can be performed.
Specialist displays present the internal and external characteristics of the designed equipment. Feature-rich transmission and doped fiber models incorporate super-stable and efficient algorithms for the most demanding design tasks including multiband, multistage, multipump, hybrid, Raman, (co-)doped fiber and waveguide amplifiers and lasers.
Complex amplifier topologies that combine different technologies (doped fibers & waveguides, Raman) can be investigated.
