Dear Mr. steven:
I want to add kerr nonliear in my simulation and caculate the
transmittance curve. For example, the nonliear index (experiment
data) n2=0.0435um^2/W, if i want to get the changing of the index
n2*I with order of 1e-3, we should use pump intensity of 0.02299
W/um^2. how should i set the amplitude of the source? In linear
simulation, i can use the "meep-fields-flux-in-box" to monitor the
power by changing the amplitude of the source. what is the
amplitude which corresponds to the real power intensity 0.02299W/
um^2 ? (the lattice constant is a=210nm)
Good luck!
