Thank you again for the examples. I have one more question. I have measurement data (transmittance from Cary 50 and specular reflection by Lambda 900). How can I correlate the simulation from FDTD with the measurement data? Right now, the simulated power spectrum at the transmission detector is so low. It doesn’t seem to increase much no matter what parameters I change (e.g. index contrast, layer number, etc).
Can you take a look for me? The colloidal photonic crystal slab I am working on has very low index contrast (delta n <0.1) between the spheres and the matrix, but has a good periodic structure. The sphere radius is about 60-80nm. I am trying to find out how optical spectra will change with sphere size, filling factor, layer number, and disorder, etc.
