In the MEEP tutorial, concerning calculating the transmission
spectral, you proposed "in order to normalize the transmission (to get
transmission as a fraction of incident power), we'll have to do two runs,
one with and one without a bend".
However, I wonder whether I can use the flux near the source for
normalization, i.e. to normalize by dividing the flux obtained at the
bottom of the vertical waveguide by the flux obtained at the source
point?
That won't work, because flux near the source point will include both the
incident wave and the reflected wave(s).
If that's wrong, how to normalize the transmission spectral of the
following structure?
port1 --------------- port2
x x
port3 --------------- port4
It is a structure from the paper "Nonlinear photonic crystal
microdevices for optical integration" of your research group. The dash
lines represent two waveguides, and the two points represent cavities.
As described in this paper, a source is fixed at port1. If I want to
calculate the normalized transmission spectral of port4, how to
normalize? What flux should the flux at port4 be divided by?
Do a normalization run with just a single waveguide and no cavities, i.e.
port1 --------------- port2
This will give you the incident flux.
