Hi,

I am running a simulation for  a grating coupler. One check I performed is to observe the sensitivity of the coupling/transmission response w.r.t the launch wavelength of the source. In the simulation, I am using a gaussian source with certain beam waist, angle and distance pertaining to a real world experiment.

I noticed that when I change the center wavelength of the source, the transmission response at the transmission monitor on the taper end of the grating shifts (image below). Theoretically, the response shouldn't change w.r.t the launch wavelength/center wavelength of the source. But why does the simulation show otherwise?

(is there a source normalization happening here that I missed out considering)

Hi Devendra

I couldnt access the learning forum. I could open it in the morning, but clicking the post button doesn't process any further. Now when I try it again, it shows that the server is under maintenance. I need to get my question answered at the earliest. Can you let me know what's going on?

Hi Devendra

Its okay on my end as I have my question answered separately.  Its just that I couldn't post on this discovery forum.

Thanks,
