Abstract

This paper reports on the use of 2D photonic crystals to design microwave waveguides. The waveguide consists of a periodic arrangement of holes, with a square or rectangular cross section, that extends along the waveguide with a central defect defined by the absence of a hole. The theoretical analysis of such a structure is based on a biorthogonal‐basis method and provides a full‐vector description of the modes guided by the defect. Our results show that such a waveguide can be designed to support only one mode at any operating frequency. This mode is a polarization doublet whose dispersion is controlled by the geometrical parameters, thus permitting the design of a novel polarization‐maintaining waveguide. © 2003 Wiley Periodicals, Inc.

A two-dimensional photonic crystal waveguide with a novel geometry is introduced. The center line of this waveguide is bent along a free-curve such that the direction of the propagating light can be changed without scattering or reflection losses. The design method is described for a triangular latt

## Abstract In this Letter a novel type of waveguide based on a photonic crystal and implemented in microwave printed‐circuit technology is proposed. The novel waveguide is obtained by introducing a line defect in a 2D photonic crystal placed inside a parallel‐plate waveguide. The resulting structu

We theoretically investigate optical coupling between a waveguide and a localized mode arising in a cavity resonator of a two-dimensional photonic crystal. By carrying out two-dimensional finite-difference time-domain calculations, we evaluate coupling efficiency by observing whispering gallery mode
