Inquiry on how to model a simple DBR fiber laser in Optisystem

[Emanuel Park Kim]

Hello,

I am interested in modelling an Erbium-doped Distributed Bragg Reflector (DBR) fiber laser. The current challenge I am facing is regarding the bidirectionality of the Fiber Bragg Gratings (FBGs). The current models I see available in Optisystem, only allow to have one input, but I would like to create a feedback loop between two FBGs that surround a section of Erbium-doped fiber (EDF) to form the linear cavity of the laser.

Is there a way to achieve such a thing? Thanks a lot!

Hello,

Thanks for providing the information.

There is a bidirectional FBG in OptiSystem by the name “Uniform FBG Sensor”. You can find it in the component library. I urge you to look at it’s Help document to correctly model it. You can use that to model your Erbium doped DBR fiber laser.

It is also possible to build bidirectional FBG using the current components in OptiSystem but this is available only upon request. And this service is only available for the licensed users. If you have a valid license, can you please share the license serial number?

Best,
Saurabh Bedi.
