| 摘要 |
The present invention relates to a wavelength-selectable device of a smaller structure capable of selecting a wavelength. The wavelength-selectable device has a waveguide substrate in which optical waveguides are built, a wavelength selector, and a movable mirror. The wavelength selector is fixed at a position where light propagating in the optical waveguide arrives, and the movable mirror is arranged to be movable between a first position where the light propagating in the optical waveguide arrives and a second position off the optical waveguide. This configuration achieves the wavelength-selectable device in the smaller structure.
