Erbium Cross Section Data

[Firat Durak]

Hello,

I am working on EDFA. I made a setup and erbium cross section data file for EDF, but i couldn’t get any good results.
Also i got an error at erbium cross section data file loading. I attached my project file
What is the problem ? May you help me ?
Thank for your attention…

Hello,

Two main things:

In your .dat file the digits are separated by commas, when they should be separated by decimal points. That’s the convention our text documents take.

Also I tried with the fiber component you had placed but the parameters you changed do not seem to give a working component. If I place a new default component and use the text file you submitted it works fine. Do you have a reference for the parameters you set? The background loss was noticeably high as well at 30 dB/km.

Cheers!

Hello Damian,

Thank for your reply. I have some documentation about my erbium doped fiber (attached file).
May you help me also about EDF parameters ?

Also i converted my data file, but i had an error “corrupted file: unexpected format”.

It seems like they do not give all of the characteristics I would need. I don’t get any error when using your data files, however here are some problems because there are two frequencies where the parameters are MUCH larger e-11 instead of e-25, you may want to look into that.

Hello,

Attachment file was my last version of project file. There was no porblem with my cross-section file. Now i have some problems with gain. There is no gain at my system. Also information about my EDF,

1)The background loss is about 23 dB/km. It was measured at 1200 nm.No information for 1300 nm.
2)The core and Er doping diameter are about 3.5 um.
3)The Erbium ion density is about 1.9E+25 (m^-3).

Hi Firat,

I’m away from the office for the next two weeks, and my ability to troubleshoot projects will be limited.
