RP Fiber Power – Simulation and Design Software for Fiber Optics, Amplifiers and Fiber Lasers

The Ultimate Tool for Passive and Active Fibers Devices

RP Fiber Power is a powerful modeling software for designing and optimizing fiber devices – in particular, fiber amplifiers and lasers as well as other types of waveguide lasers, but also fiber couplers, multi-core fibers, helical core fibers and tapered fibers.

The software offers both efficient power propagation and full numerical beam propagation. Ultrashort pulse propagation can also be studied, for example in fiber amplifier systems, mode-locked fiber lasers, telecom cables and automatically optimized pulse compressors.

RP Fiber Power is

  • an enormously versatile tool for power users,
  • but at the same time (particularly since V6 with custom forms) also very suitable for users who are not (or not yet) experts in the field.

It is a must-have for anyone seriously dealing with fiber devices – be it in industrial development, scientific research or in education. Its user interface combines uttermost flexibility with an easy start. It is therefore equally well suited for efficient routine checks and for most sophisticated simulation work.
