Thanks a lot Damian!
The file is attached and the reference I’m trying to imitate is:
http://iopscience.iop.org/2040-8986/14/5/055001
I’m trying to simulate the design in Fig 2(a)(the linear ring not the one with the non-linear material … at least as a beginning :))
which is a dielectric ring with n = 1.12 on a Silver wafer using Drude model.
The dimensions are as follows:
Rcore = 100 nm
Waveguide width = 50 nm
gap between ring and waveguide is 10 nm.
Actually, using the previous design, I can’t even determine the effective index of the modes that’ll propagate in the structure … I get no modes!
and please if an example for a plasmoni ring (the ring itself is metal) is added to the manual or OptiFDTD site, that will be very useful …
Thanks a lot for your help,
