Abstract

We study theoretically slow light structures exhibiting zero group velocity in middle of the Brillouin zone. We find that in order to exhibit a mid-band group velocity point in its dispersion relation, a slow-light structure must possess two distinct optical paths supporting counter-propagating power flows. This is in contrast to conventional slow-light structures which exhibit zero group velocity only at the edge of their Brillouin zone, which indicates the emergence of a standing wave.
