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.

 
Hybrid EDF/Raman Amplifier

Complex amplifier topologies that combine different technologies (doped fibers & waveguides, Raman) can be investigated.

Applications

  • Perform bidirectional Raman modeling with all signal-pump-noise-backscatter interactions (stimulated and spontaneous Raman scattering).
  • Import an OTDR trace representing local insertion loss and reflections for true characterization of installed fibers.
  • Model sophisticated Er/Yb doped or co-doped fiber amplifiers and lasers with flexible input parameter specifications including Giles parameters or gain and absorption cross-sections, refractive index and doping profiles or wavelength-dependent overlap factors, wavelength-dependent Rayleigh backscatter and background loss, two or three-level parameters.
  • Investigate concentration quenching, excited-state absorption, gain temperature-dependence, and spectral hole burning doped-fiber amplifiers.
  • Design co-doped waveguide amplifiers from waveguide dimensions upwards, and including excited-state absorption, up conversion, cross-relaxation, and pair-induced interactions in co doped waveguides.
  • Stimulate full interaction between amplifier stages, including pump reuse and ASE-pumped amplification.
  • Characterize amplifier performance and BER estimation using specialist instrumentation.
  • Abstract doped-fiber designs to pump-power dependent Black-Box models.

  • and many more. (Explore application examples in detail!)
 
Raman Pump Optimization

Powerful optimization tools can be applied to set pump wavelengths and powers of multi-pump Raman amplifiers.

EDF Power Profile

Visualizing the distribution of power, noise or inversion along the (doped) fiber provides useful information to improve the amplifier design.
