ABSTRACT:
A wavelength-selective optical device includes an optical fiber having a grating portion where a refractive index of medium is periodically changed; a light input portion where light is supplied to the optical fiber; a light output portion where light with a specific wavelength to be output from the optical fiber is taken out; and means for applying a stress to the grating portion. By adjusting the stress applied to the grating portion, a reflection center wavelength of the grating portion is changed to reduce transmission losses.
