Analysis of Higher Order Channel Dropping Tunneling Processes in Photonic Crystals

A theoretical analysis is given for a higher order channel drop tunneling structure composed of two horizontal channels and a resonator system with two vertical multi-mode cavities in a two- or three-dimensional photonic crystal. Criteria for a complete transfer are derived for the application of wavelength division multiplexing. Compared to the resonator system with two single-mode cavities or a single multi-mode cavity, the present resonator system improves the transport properties.
