RP Fiber Power – the versatile Fiber Optics Software

An Amazing Tool

RP Fiber Power software

This amazing tool is extremely helpful for the development of passive and active fiber devices.

ASE

Watch our quick video tour!

Single-mode and Multi­mode Fibers

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:

special fibers

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, …

fiber devices

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

Laser Design Services

The quality of a laser product is largely determined by its design and not just by the used parts.

Developing a good design requires a high technical competence and experience. Dr. Paschotta from RP Photonics offers can greatly help by

  • analyzing and amending our design goals, and working out complete design specifications
  • identifying the best suited technology (e.g. bulk or fiber laser)
  • working out a solid design, often based on numerical modeling
  • identifying possible problems early on, which allows for efficient solutions
  • giving you further advice as needed when you test your prototypes

Note: with a trial-and-error approach you may waste a lot of time and resources. (Also consider time to market!) Therefore, competent help is the key for cost-efficient and lower-risk developments.

You may also involve us only if you got into trouble, but coming earlier is usually better.

Banner 37:

Technical Writing

In the laser and photonics industry, there is a lot to write:

  • A clearly written user manual belongs to every high-quality product.
  • A research proposal (e.g., for an SBIR project) needs to be convincing in all respects.
  • Venture capital firms need to be properly informed on the developed technology, its potentials and limitations, competing approaches, etc.

Get competent help!

You may try to write yourself, but keep in mind that involving a top expert such as Dr. Paschotta from RP Photonics can have many advantages:

  • He is most experienced in writing, producing high-quality documents efficiently.
  • He may bring in new perspectives and ideas.
  • You save time which you can spend on other things.

Just contact RP Photonics to find out what we can do for you!

Banner 38:

Evaluation of Technologies

In the laser and photonics industry, it is often essential to obtain competent evaluations of certain technologies:

  • A CTO of a laser company needs to know whether some new technical idea is worthwhile pursuing. Maybe there are some hidden problems?
  • A user of lasers is told about a great new laser architecture – but will it really serve her needs?
  • Venture capital firms need to find out what the potentials and limitations of certain technologies are. We call that applying due diligence.

Get help!

Involving a top expert such as Dr. Paschotta into technology evaluations can have many advantages:

  • He has a good overview on many technologies and their potentials and limitations.
  • His analytic mind allows him to develop a balanced perspective, taking into account all relevant aspects.
  • He is well trained in writing useful reports.
  • He may bring in new perspectives and ideas.

Just contact RP Photonics to find out what we can do for you!

Banner 39:

Independent Advice on Products

If you buy things like laser crystals, optical fibers or whole laser systems, many questions can arise:

  • What length and doping level should I choose?
  • What is the best suited material?
  • How do these product specifications relate to my requirements?

Get help!

You need an expert

  • who is technically very competent,
  • who takes care to analyze your needs,
  • who can identify possibly critical issues,
  • and who gives you impartial advice, not influenced by possible commissions, for example.

This is one of the offers of RP Photonics. Such work costs something, but far less than what you can waste by buying the wrong things. Just contact us before making critical purchase decisions!

Banner 40:

Buyer's Guide

On our website, you find not only the famous encyclopedia, but also the RP Photonics Buyer's Guide:

RP Photonics Buyer's Guide

  • Find suppliers for many hundreds of photonics products.
  • Enjoy high-quality product information (checked listings) and the convenient user interface.
  • Use high-quality technical information of the encyclopedia nearby.

Is it actually surprising that you find the best buyer's guide at the same place as the best photonics information source?

Banner 41:

Trouble with Specifications

Specifications for lasers and other photonics products are essential for the process of buying such things. Nevertheless, many do not properly deal with them:

  • Many product specifications by suppliers lack quality – they are incomplete, not sufficiently clear, etc.
  • Buyers are often not aware of what they really need. For example, they forget essential requirements.

Various problems can arise:

  • Due to a lack of clarity, tedious communications between supplier and buyer are required.
  • Product specifications raise expectations which cannot be met.
  • Conflicts can arise over such issues.

Our Photonics Spotlight article and our encyclopedia article on laser specifications give you important hints. In case of doubt, contact RP Photonics to get competent and impartial advice.

Banner 42:

Business Disputes

Occasionally, serious disputes arise, e.g. when a company purchases a laser from some supplier. Conflicting views may occur concerning questions as:

  • Is the beam quality consistent with the somewhat vague specifications?
  • Is it normal that the laser pulses exhibit substantial timing jitter?
  • Should it be considered as acceptable that the laser stays within specifications only if its alignment is optimized quite often by the user?

Mediation

Going to court is usually the last thing you want to do – but how else to resolve a conflict?

Mediation is a much more attractive approach. Only, you need to find a mediator

  • who fully understands the technical matters, and
  • who can be trusted to be impartial and fair.

Dr. Paschotta from RP Photonics offers such services. Your chance is to reach a fair resolution with far less time and money than at court.

Staff Training

Up-to-date technical know-how is the key to success in photonics. RP Photonics offers high quality training courses at your location:

  • Courses on basic, intermediate or advanced topics – tailored to your needs and already existing knowledge.
  • Boost the competence of your whole team within a few days!
  • Get your questions answered straight away.
  • Stimulate new ideas and motivate the whole team.

Dr. Paschotta from RP Photonics

  • is a top expert in laser technology, fiber optics and nonlinear optics, also highly respected and trustworthy partner,
  • can explain complicated things in helpful ways, and
