RP Fiber Power – Simulation and Design Software for Fiber Optics, Amplifiers and Fiber Lasers
Here, you find a number of video demos, various detailed demonstration case studies and various nice graphics made with the software.
Case Studies with RP Fiber Power
Case Studies Using Power Forms
We first present some examples of typical work with our Power Forms:
We test how the mode structure of such a fiber reacts to certain changes of the index profile, e.g. to smoothening of the index step.
We investigate how intermodal dispersion of a multimode fiber can be minimized with a parabolic doping profile.
Amplified spontaneous emission (ASE) turns out to be a limiting factor, requiring a dual-stage amplifier design.
Specifically, we deal with deformations of the pulse shape due to gain saturation. These can be minimized by pre-distorting the input pulses.
Here, we optimize an amplifier for equal output powers of signals spanning a substantial wavelength range. There is a trade-off between power efficiency and noise performance.
We study various aspects of amplified spontaneous emission (ASE) in ytterbium-doped fibers – for example, why it is different in forward and backward direction, how the fiber length can have a crucial impact, and how the fiber core diameter matters.
We develop a double-clad fiber amplifier with high gain, where we have to care about limiting losses by ASE.
We explore how to realize Yb-doped fiber lasers emitting at the tricky wavelength of 975 nm. This turns out to be challenging for devices with double-clad fibers due to ASE at longer wavelengths.
We explore how we can spectrally broaden light pulses by self-phase modulation in a fiber and subsequently compress the pulses using a dispersive element. A substantial reduction in pulse duration by more than an order of magnitude is easily achieved, while the pulse quality is often not ideal.
We explore the regime of parabolic pulse amplification in an Yb-doped single-mode fiber. We find reasonable operation parameters and investigate various kinds of limitations, e.g. concerning the nonlinear pulse compression.
#amplifiers #pulses #nonlinearities
We let two soliton pulses collide in a fiber. Surprisingly, they survive such collisions, even if we involve solitons of higher order.
We investigate to which extent soliton pulses could be amplified in a fiber amplifier, preserving the soliton shape and compressing the pulses temporally.
These case studies demonstrate how useful the modeling is for the development of fiber amplifiers and lasers, for example.
(More example cases with Power Forms are in preparation!)
Case Studies Using Demo Scripts
The following example cases are all related to the demo scripts delivered with the software. That approach can be applied even to most special cases.
A first set of examples illustrates the power of the mode solver and the numerical beam propagation:
Further demo files show how to simulate fiber amplifiers and lasers (only steady-state calculations):
Here are some examples of dynamic simulations:
Next, there are demonstrations for simulating the propagation of ultrashort pulses:
Finally, a demonstration for generating output in other forms:
Even more demo files (in total more than 70) are delivered with the software. As a user, you can simply copy demo scripts and modify them according to your needs. However, you may also easily generate new scripts using the interactive forms.
