The point-defect coupling under the tight-binding approximation is introduced to describe
the behavior of dispersion relations of the guided modes in a single photonic crystal …

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 …

Self-collimated beams and photonic bandgap mirrors in photonic crystals are evaluated for
applicability in an on-chip interconnect system. Simulations using the plane-wave expansion …

The behavior of two nearby straight photonic crystal waveguides is analyzed. It is shown that
the two guides, considered as a single system, may realize a very efficient wavelength …
