Hello Scott,

Thank you for your reply.
I have tried to model the entrire laser system as one piece but I came across some difficulties when calculating the overall mode of the system as well as the coupling stength and length. I did it long time ago but I thougth to ask again here if is even feasible….
So, based on your answer the composite structure of two laterally coupled waveguides that can function as a single cavity is not possible to be simulated with this software,right?

Thanks,
Konstantina

Hallo everyone,

Is the free version of OptiFDTD capable of simulating Evanescent waveguide couplers?
Below are some images or what I would like to simulate.

Thank you!

Hi Scott,

thank you for your indepth answer and sorry for the late responce.

I would like to ask something else. Is the free version of OptiFDTD capable of simulating Evanescent waveguide couplers?
Below are some images or what I would like to simulate.

Thank you for your time in advacne.

Dear Jing,

thank you for your answer.
Attached is an image showing two laterally coupled semiconductor lasers of different lengths.

That is what I would like to simulate.
any help would be greatly appreciated.

Thanks,
Konstantina
