I'm dealing with a very simple problem that has been very frustrating for me! I would appreciate if any one can assist me with that.
I am performing a simulation of light coupling (transmission) between two optical fiber in which there is a gap amid them using RF module of COMSOL 3.5 (RF Module>In-Plane Waves>TE Waves>Harmonic propagation). My fiber type is SMF, my light wavelength is around 1um and the gap is around 200um.
when I set the wavelength to 1um, COMSOL simulation does not show light propagation perfectly! And when I increase wavelength to at least 5um, the simulation starts to show a good graphical results in which shows light coupling between two fibers.
However, the light that we already use in the lab is close to red (lambda is near 800um). But with this wavelength COMSOL does not show any good result!!
Do you have any solution for my issue to improve my simulation and compare it with experiments?
Please do not hesitate to contact me for further information.
Thanks
