ABSTRACT:
A photonic crystal2with plasticity is arranged by making microspheres of silica or barium titanate or air bubbles be contained in a gel substance. When an external force is applied to this photonic crystal, photonic crystal2deforms and the photonic band gap is readily changed thereby. When the photonic band gap changes, the passage of light of a specific wavelength is restricted. Light of a desired wavelength is thus output from photonic crystal2. With this invention, this wavelength can be varied readily by means of an external force.
