Abstract

A honeycomb waveguide network for parallel signal processing, consisting of single-mode symmetrical Y junctions, is proposed. In this waveguide network, input guided-wave amplitudes are divided and then combined with the amplitudes of the adjacent waveguides. It is shown that the operations of spatial filtering, such as smoothing, edge extraction, and edge enhancement, can be performed. An example of the honeycomb waveguide network is discussed.
