Complete photonic bandgaps in supercell photonic crystals
/ Authors
/ Abstract
We develop a class of supercell photonic crystals supporting complete photonic bandgaps based on breaking spatial symmetries. One member of this class supports a complete bandgap for n<inf>high</inf>/n<inf>low</inf> = 2.1 the lowest known index-contrast ratio in 2D.
