The trapping and dropping of photons through localized cavity modes in three-dimensional layer-by-layer photonic crystal structure were studied. Selected frequencies from the waveguide mode were dropped by creating acceptor- and donor-like cavities coupled to a highly confined waveguide (HCW). Tunability of the demultiplexing structures was achieved by changing the properties of cavities and the coupling between the cavity and the HCW.
