Abstract
A multi-mode waveguide is provided, the waveguide configured to support at least two degenerate modes of electromagnetic fields. The waveguide comprises an input node configured to couple electromagnetic fields into the waveguide. An output node is configured to couple electromagnetic fields out of the waveguide. A perturbation is configured to couple the two degenerate modes within the waveguide. The input node and the output node are positioned such that coupled degenerate modes clockwise and counter-clockwise propagating waves within the waveguide with at least two transmission minima. A waveguide device comprising a plurality of such multi-mode waveguides is also provided, the waveguide device having a plurality of transmission minima.
