摘要

We demonstrated perfect light absorption inultra-thin optical nanocavity made of a percolation aluminum film and a thin silicon film deposited on aluminum metal surface. Critical coupling to the optical nanocavity results in complete light absorption at specific wavelength, determined by the silicon film thickness. Due to light penetration into aluminum metal on top and bottom, the optical nanocavity silicon layer thickness can be one order of magnitude less than the perfect light absorption wavelength.
