By John Oncea, Editor Photonic gap materials, or photonic crystals, are structures with a periodic dielectric profile that prevent light from propagating at certain wavelengths. This creates a "gap" where light cannot travel, offering potential for optical devices like filters and waveguides. Formed in Tulsa, OK in 1967, the Gap Band was based around the Wilson brothers – Charlie, Ronnie, and Robert.
