We study double degenerate defect states in the band gap of the two-dimensional photonic crystal which can be split by the Jahn-Teller distortion of the lattice. We present a group theoretical analysis of the splitting effect. The effect is supported by supercell plane wave model and by the finite difference time domain technique. We suggest ways for using the effect in photonic switching devices and in waveguides.
