        Thank you for your response. That would be great if you can find me some examples. I need to decide if we should purchase the software or not. I am not sure if FDTD is a good method for simulating optical response of a limited thickness PhC slab.

        Hi, Aurelien

        Great. The first example is very similar to to what I am planning to design. I am still learning to use the software. But I will let you know how it turns out.

        Many thanks.

        Serena

        Hello, Aurelien

        I am wondering if you’ve received my email with the original data. My 64-bit trial license is expiring, but I haven’t been able to simulate anything close to the measurement data. There are too many layers in the z-direction (>80 layers and 15um thick). Will FDTD be a good solution for this type of structure?

        Hello, Aurelien

        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.

        Great. I just sent some files to your email. Thanks again.
