General Framework for Twisted Bilayer Photonic Crystal with Interlayer Coupling and Far-Field Response

Shupeng Xu, Dun Wang, Ritesh Agarwal

We develop a general theory for twisted bilayer photonic crystals that takes into account both far-field response and near-field coupling. The theory is based on the framework of a…
