What can you do with RP Fiber Power?

RP Fiber Power is a powerful software for simulation, design and optimization of fiber devices – in particular, fiber amplifiers and lasers as well as other types of waveguide lasers (and even many bulk lasers) , but also fiber couplers, multi-core fibers, helical core fibers, tapered fibers and pulse compressors.

RP Fiber Power can be applied to analyze and optimize a wide range of devices:

Devices	Examples of Applications
single-mode and multimode fibers	calculate mode properties such as amplitude distributions, effective mode areas, effective indices, chromatic dispersion calculate fiber coupling efficiencies simulate effects of bending, nonlinear self-focusing or gain guiding on beam propagation, higher-order soliton propagation optimize supercontinuum generation
fiber couplers, double-clad fibers, multi-core fibers, planar lightwave circuits	simulate pump absorption in double-clad fibers study beam propagation in fiber couplers study light propagation in tapered fibers analyze the impact of bending investigate leaky modes
fiber amplifiers	check how rapidly pump light is absorbed (considering pump saturation effects) and how signals are amplified study the gain and saturation characteristics (continuous-wave or pulse amplification) investigate energy transfers in erbium/ytterbium-doped amplifier fibers assess the impact of amplified spontaneous emission in single amplifier stages or in multi-stage amplifier systems study the influence of quenching effects
fiber-optic telecom systems	analyze dispersive and nonlinear signal distortions (e.g., produce an eye diagram and do statistical evaluations) check the impact of amplifier noise optimize nonlinear management and placement of amplifiers
fiber lasers	analyze and optimize the power conversion efficiency assess the achievable wavelength tuning range investigate Q switching dynamics assess performance-limiting effects and the risk of fiber damage
ultrafast fiber lasers and amplifiers	study pulse formation mechanisms and stability ranges assess the impact of nonlinearities and chromatic dispersion simulate parabolic pulse amplification or chirped-pulse amplification optimize dispersive pulse compression assess the sensitivity to optical feedback
pulsed and ultrafast bulk lasers and amplifiers	study Q switching simulate mode-locking behavior find the required characteristics of saturable absorbers analyze the feedback sensitivity assess the stability limits of regenerative amplifiers simulate parabolic pulse amplification or chirped-pulse amplification

Such computer simulations give you a very detailed insight into the inner workings of devices, including a complete quantitative understanding. That is crucial, for example, for really understanding how these devices work, and for assessing the risk of damage or performance-degrading effects. And that is indispensable for efficient research and development.

The physics features offered by RP Fiber Power:

LP mode solver – highly efficient, works well even with thousands of modes
power propagation – efficient and reliable even with many pump and signals waves, ASE, etc.
numerical beam propagation
dynamic simulations with arbitrary time dependencies of input powers
ultrashort pulse propagation, again with full flexibility

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.

RP Fiber Power V8 – a Breakthrough of Usability!

With its crucial new feature of Power Forms, this Version reaches a new level in terms of combining power, flexibility and ease of use. Essentially, these are easy-to-use forms that we provide for a nice set of extensible simulation models, covering a wide range of application areas of the software.

Great Handling

Start your first simulations in no time!

example for a Power Form

Figure 1: The beginning of one of the Power Forms.

Just fill out the appropriate form, e.g. the one for ultrafast fiber amplifier systems. Set the relevant parameters and the desired outputs (mostly diagrams). Then run the simulation and inspect the beautiful and highly informative output!
You can simulate even complex fiber amplifier systems with multiple amplifier stages, each with multiple pump sources, multiple input signals (continuous wave, short pulse, or ultrashort pulse), etc.
The forms are very nicely designed to be easy to use despite their richness of features. For example, currently irrelevant parts of the forms are hidden, and many output fields display helpful hints when the mouse pointer is over them.
Comprehensive documentation is available with a single keystroke. You can read exactly what is simulated and how to configure everything.

Amazing Flexibility

Get what you need - even what we did not anticipate!

Form-based user interfaces are common – but often not flexible enough to do real work. For example, what if you need an extra curve on a graph, an entirely new graph, or an advanced simulation with additional inputs?

With RP Fiber Power V8, we have made a breakthrough in how to achieve great flexibility:

To add an extra curve to a diagram, just add a single line of script code to the form. (We are happy to help you.)
For an entirely new diagram, enter a few lines of script code into the form.
For extensive post-processing of the results, including generating output files in a custom format, call an external custom script with a single line of code in the form.
For even more complex extensions, you can easily create a customized version of a form. This can, for example, have additional input and output fields and perform additional calculations related to them.
For doing very special things, outside what is covered by all our Power Forms, there is still the option to develop your own Simulation Scripts, which can also be equipped with forms for easy handling.

And our diligent technical support means that you will not be left alone!

Not a simulation guru yet? Don't worry:

If you can build a laser or amplifier in reality, you can surely simulate it with this software.
When in doubt, the high-quality documentation will tell you exactly what is needed, what effects the model takes into account, etc.
Our diligent technical support won't leave you alone if you encounter problems! We support you even beyond software-specific problems.

Your personal professional development can soon be greatly enhanced: if you become the one who quantitatively understands these devices, you will play a key role in your team.

Start Doing Excellent Development Work

You should now get the right tool to take your design work to a new level of quality, efficiency, and creativity:

Before ordering parts, testing your prototype, diagnosing and troubleshooting in the lab, simulate your prototype laser or amplifier on your PC. There you can eliminate many problems in no time!
Only then is it time to order the parts and build and test the device in the lab.
If you encounter problems later, use the simulations again to quickly diagnose and find solutions.

You can soon save a lot of time and money, and also develop new creative solutions.

Required Computer

You only need an ordinary PC running under a 64-bit version of Windows 10 or 11, for some applications with reasonable CPU speed and memory (e.g. 8, 16 or 32 GB). For using the Power Forms, it is good to have a large screen.
