Abstract

The spectral dependence of the optical transmission through close-packed monolayers of silica (a-SiO2) microspheres covered with different amounts of amorphous silicon (a-Si) is studied. The strong dips in the transmission can be understood by the coupling of the incident electromagnetic field into the modes of the combined photonic slab structure consisting of the close-packed lattice of a-SiO2 microspheres and a-Si. The dependence of the transmission minima positions on the a-Si thickness and the angle of incidence agree quite well with model calculations.
