EDFA simulation problem

[Juan E. GARCIA]

I am trying to simulate a circuit, but I have problem and the simulation does not finish.

The error says:
“CIDF Schedule: error occured while calculating, component Erbium Doped MM Fiber
Error in Erbium Doped MM Fiber: Parameterized signal at input port.
Calculation failed!”

Help me, please. What can I do in this case?

Hi Juan,
I have created a simple project (attached) for you. It is running and you can see the output spectra as expected.
Hope you can use it as a start point to move forward with your project.

thanks
Mohamed

Thank you very much for your help Mohamed, but I have another problem, I don’t know why the program doesn’t want to open the file you send me. When I try to open it, there is a message “Failed to load document from storage”. Would you mind sending me the document by mail?

[Mohamed A. A. Abouseif]

No problem.
which version of OptiSystem you are using?
I built it on Optisystem15.
so you can open it for the same or newer version.
just let me know to try to find a solution for you.

thanks,
Mohamed

It is the same, I am using the 30-day evaluation version. I installed the application the last Thursday.

I tried again, but it was impossible. Thank you very much for your aid. Can you send me a picture from the schematic. I am practicing some circuits trying to fix the problem with the general circuit.

here is the schematic and the output results.

good luck

try to combine pump laser with another CW laser using combiner then connect the output of the combiner to the fiber.
let me know
thanks

I have tried some ways, but I don’t know if the problem is with my computer. I don’t know why this error. I just practiced the diagram from the application of this website, and the problem appears.

[Mohamed A. A. Abouseif]

did you try the combiner with CW laser?

[Juan E. GARCIA]

Yes, the problem persists. 🙁

there is a built-in example similar to this project titled “MM EDFA ExampleAllModesEquallyExcited.osd”
try to open it !!

Hi Juan,
There is an example titled “MM EDFA ExampleAllEquallyExcited.osd”
Have you tried it? it similar to what you need. then you can delete the CW Laser and the pump coupler.
let me know.
good luck

thanks
