How can i get the desired fiber guided mode and plasmonic mode in SPR-PCF?

Problems about acousto-optic coupling in Comsol, how to check whether the moving mesh is correct?

I’m trying to reproduce the acousto-optic coupling simulation in the paper Frequency–angular resolving LiDAR using chip-scale acousto-optic beam steering. LNOI(lithium niobate on insulator) is...

How to get LP fiber modes directly from Comsol?

Hi there, I'm new to modelling with comsol. I would like to ask if it is possible for comsol to output linearly polarized (LP) modes? I tried modelling a simple single mode fiber with an enlarged...

Using mode analysis in study and Electromagnetic Waves, Frequency Domain ,comsol calculates effective index and mode profiles

Maliha Iqbal

(@Mojtaba Dehghani Firouzabadi) i did the same but i did not get the desired results

Please send me an Email to send you some files

Mojtaba Dehghani Firouzabadi my email is "[email protected]"

ok , I sent it

how can we combine fiber optic and a plasmonic material in order to expect to

see a combination of fiber and plasmonic modes in the resulting

structure?
