    Abstract: If an external force is exerted on a plastic photonic crystal by a piezoelectric device (3), the photonic crystal (2) deforms and the photonic band gap easily varies. As the photonic band gap varies, the passage of light of specific wavelength is limited. As a result, light of desired wavelength is sufficiently varied and outputted from the photonic crystal (2), and the light is taken out from an output window (6) to the outside. The scale of the variable wavelength light source is small since a plastic photonic crystal (2) for varying wavelength sufficiently even though the crystal is small is used and the light source and photonic crystal are accommodated in a unit.

    Abstract: A photonic crystal 2 with 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 crystal 2 deforms 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 crystal 2. With this invention, this wavelength can be varied readily by means of an external force.

    Abstract: Th end face (7a) of an optical fiber (7) and the end face (8a) of an optical fiber (8) are disposed in a V-groove (23) in a base (21) opposite to each other and a specified distance apart. A solution (27) serving as the material of a photonic crystal and containing fine particles is dripped into a space (25) defined by the end face (7a), the end face (8a) and the V-groove (23). Accordingly, a photonic crystals are respectively grown from the end face (7a) and the end face (8a) to thereby form optical control units containing photonic crystals (2) at the end face (7a) and the end face (8a) respectively.

    Abstract: A photonic crystal (2) which comprises a material in a gel form and, arranged in the material, a plurality of micro-spheres of silica or barium titanate or micro pores. The application of an external force transforms the photonic crystal (2), which in turn changes the photonic band gap thereof. The change of the photonic band results in the restriction of the transmission of a light having a specific wave length through the photonic crystal, which allows the output of a light of a desired wave length from the photonic crystal (2). The photonic crystal can easily change the wavelength of a light outputted therefrom by the change of an external force applied thereto.

    Abstract translation: 一种光子晶体(2),其包含凝胶形式的材料并且在材料中布置多个二氧化硅或钛酸钡或微孔的微球。 施加外力会转换光子晶体(2),这又会改变其光子带隙。 光子带的变化导致限制具有特定波长的光通过光子晶体的传输,这允许从光子晶体(2)输出期望波长的光。 光子晶体可以容易地改变由其施加的外力的变化而输出的光的波长。
