Single-beam holography for Ag nanoparticle-embedded two-dimensional binary metallodielectric photonic crystals.
Absolute photonic bandgaps of photonic crystals can be increased by reducing the structural symmetry and/or by enhancing the refractive index contrast. We have experimentally demonstrated a single-beam holography for creating Ag nanoparticle-embedded 2D binary photonic microstructures by adding a different diameter rod in the center of each original 2D honeycomb lattice for simultaneously realizing both symmetry reduction and the enhancement of the index contrast of PC structures.
