The coupling of higher-order modes of broad periodic waveguides emerges when using photonic crystal waveguides. The specific idea of critically coupling such modes to generalize slow light and flat bands is examined for its various merits, notably to form open resonators. The coupled-mode-theory (CMT) also provides a simple description of spontaneous emission in them.
