Abstract

Splitting of the double-degenerate defect states in the bandgap of the two-dimensional photonic crystal by means of symmetrical distortion of the lattice is studied. The effect is analogous to the static Jahn–Teller effect in solids. We propose a device that uses the effect to tune the light propagation through a 90°-bend waveguide. The resonant coupling of the photon modes at the corner can be tuned by the symmetry and magnitude of the distortion of the lattice.
