tight binding theory

Hi everyone.
could anyone know what is tight binding theory in
coupled cavity photonic crystal waveguides?

Hi!

Well, tight binding theroy comes from theoretical material science and means basically how you treat the electrons in the material you are looking into. I don't know what the means especially for photonoc waveguides but there are certainly books to this topic. I think it is even treated well in standard literature like Jacksons's Calssical Electrodynamcis. Or maybe look for books on Material Science like Ashcroft&Mermin's Solid State Physics. The second one might be the one of choice.

Hope that helps.
