摘要	The present invention relates to an optical device and the like which can facilitate a fine adjustment for an optical waveguide type diffraction grating device. The optical device includes a flexible member in which the optical waveguide type diffraction grating device is secured to a predetermined position, and bending means for applying a stress to said optical waveguide type diffraction grating device by bending said flexible member. The optical device changes the optical characteristics of the optical waveguide type diffraction grating device by adjusting the stress applied thereto by the bending means, to thereby perform easily various functions such as optical multiplexing, optical demultiplexing, path changing, and adjustment of dispersion characteristics.
