An Amazing Tool
This amazing tool is extremely helpful for the development of passive and active fiber devices.
Watch our quick video tour !
Single-mode and Multimode Fibers
Calculate mode properties such as
amplitude distributions (near field and far field)
effective mode area
effective index
group delay and chromatic dispersion
Also calculate fiber coupling efficiencies; simulate effects of bending, nonlinear self-focusing or gain guiding on beam propagation, higher-order soliton propagation, etc.
Arbitrary Index Profiles
A fiber's index profile may be more complicated than just a circle:
Here, we "printed" some letters, translated this into an index profile and initial optical field, propagated the light over some distance and plotted the output field – all automated with a little script code.
Fiber Couplers, Double-clad Fibers, Multicore Fibers, …
Simulate pump absorption in double-clad fibers, study beam propagation in fiber couplers, light propagation in tapered fibers, analyze the impact of bending, cross-saturation effects in amplifiers, leaky modes, etc.
Fiber Amplifiers
For example, calculate
gain and saturation characteristics (for continuous or pulsed operation)
energy transfers in erbium-ytterbium-doped amplifier fibers
influence of quenching effects, amplified spontaneous emission etc.
in single amplifier stages or in multi-stage amplifier systems, with double-clad fibers, etc.
Fiber-optic Telecom Systems
For example,
analyze dispersive and nonlinear signal distortions
investigate the impact of amplifier noise
optimize nonlinear management and the placement of amplifiers
Find out in detail what is going on in such a system!
Fiber Lasers
For example, analyze and optimize the
power conversion efficiency
wavelength tuning range
Q switching dynamics
femtosecond pulse generation with mode locking
for lasers based on double-clad fiber, with linear or ring resonator, etc.
Ultrafast Fiber Lasers and Amplifiers
For example, study
pulse formation mechanisms
impact of nonlinearities and chromatic dispersion
parabolic pulse amplification
feedback sensitivity
supercontinuum generation
Apply any sequence of elements to your pulses!
… and even Bulk Devices
For example, study
Q switching dynamics
mode-locking behavior
impact of nonlinearities and chromatic dispersion
influence of a saturable absorber
chirped-pulse amplification
regenerative amplification
RP Fiber Power is an extremely versatile tool!
Mode Solver
For example, calculate
amplitude and intensity profiles
effective mode areas
cut-off wavelengths
propagation constants
group velocities
chromatic dispersion
All this is calculated with high efficiency!
Beam Propagation
Propagate optical field with arbitrary wavefronts through fibers.
These may be asymmetric, bent, tapered, exhibit random disturbances, etc.
See our demo video for numerical beam propagation .
Laser-active Ions
Work with the standard gain model, or define your own level scheme!
Can include different ions, energy transfers, upconversion and quenching effects, complicated pumping schemes, etc.
Multiple Pump and Signal Waves, ASE
Define multiple pump and signal waves and many ASE channels – each one with its own transverse intensity profile, loss coefficient etc.
The power calculations are highly efficient and reliable.
