photonic crystal
(redirected from Photonic bandgap)

    Also found in: Acronyms, Wikipedia 0.01 sec.
photonic crystal
A nanostructured array of holes used as an optical semiconductor. Just as electronic bandgaps prevent electrons from passing through, photonic crystals create photonic bandgaps that confine light. This technology increases the efficiency in optical fibers and allow microscopic lasers to be built. It is also expected to be used in the construction of photonic circuits that can stand alone or be integrated into semiconductor circuits. See bandgap.
photonic crystal [fə‚tän·ik ′krist·əl]
(optics)
A macroscopic, periodic dielectric structure that possesses spectral gaps (stop bands) for electromagnetic waves, in analogy with the energy bands and gaps in regular semiconductors. Also known as photonic band-gap material.
