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

The Ultimate Tool for Passive and Active Fibers Devices

Wouldn't you like to

  • quantitatively understand fiber lasers & amplifiers and passive fiber devices
  • profit from competent support
  • reduce trial & error in prototype development
  • minimize your development cost
  • optimize time to market

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.

Ultrashort pulse propagation can also be studied, for example in fiber amplifier systems, mode-locked fiber lasers, telecom cables and automatically optimized pulse compressors.

This software 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.
