I am simulating the reflection and transmission properties of a 1D photonic crystal with a gold film on top. I am also interested in the decaying electric fields across the device. I have attached my file here. toplighttest_lumerical.fsp (1.2 MB) I have a couple of questions listed below.
- In my 1D field monitor, the fields become slanted and the amplitude is not 1 (even though the plane wave source amplitude is set to 1). I believe this is due to the monitor picking up the plane wave source and reflected light, but I want to double check to make sure it is not an error. I took the device out and ran the sim, resulting in an E field amplitude of 1 ±1%. Shouldn’t this be exact? I noticed that the mesh override region made a small difference in the results.
- When I switch the background index from air to water (RI=1.335), the resonance peak only changes in intensity, not in spectral location (opposite of what I expected). Could this indicate a faulty setup somewhere?
Thanks for the help!
