While light is confined vertically by index guiding, a triangular superlattice monolayer of spheres was found to exhibit a photonic band gap below the light cone, thereby preventing light from propagating laterally. A gap map of this structure is presented. We propose a possible waveguide configuration that yields two non-degenerate defect modes lying within the photonic band gap. Such a structure may be particularly interesting for coupling light into self-assembled colloidal photonic crystals. %G English %L hal-00437956 %U https://hal.science/hal-00437956 %~ CNRS %~ UNIV-MONTP2 %~ GES %~ UNIV-MONTPELLIER %~ UM1-UM2
