Abstract

We report on the design and fabrication of metal-dielectric photonic band-gap structures (MDPBGs) with high transmission and broad spectral bandwidth in the visible range. Using the complex refractive index measured by spectroscopic ellipsometry, we have designed structures with an aperiodic thickness distribution which show a flat passband transmission (64% ± 1.5%) over more than 150 nm within the visible spectrum. Using e-beam deposition, we demonstrate the growth of continuous 12 nm Ag layers on Al₂O₃, and MDPBGs with five periods of Al₂O₃/Ag/Al₂O₃ that show more than 49% ± 2.5% transmission and at least 150 nm bandwidths. When compared to dielectric-dielectric stacks, the use of metallic layers provides excellent out-of-band rejection, in particular beyond the IR edge where the MDPBG acts collectively as a metallic solid. Such structures could thus be used as hot mirrors with extremely high and broad out-of-band rejection.
