A periodic multimode waveguide provides contradirectional feedback of all its modes. The relative constancy of feedback strength results in regular bands and stripes of minigaps at zone edges. A critical coupling strength was recently shown to flatten the bands and provide collective slow light. We connect these aspects to the “Littrow lasing” geometry and to spontaneous emission modification on the application side or to “dark modes” on the theoretical side.
