PROBLEM TO BE SOLVED: To provide a wavelength selective device capable of selecting a wavelength in a smaller structure. SOLUTION: The wavelength selective device (320) is equipped with a waveguide substrate 321 in which an optical waveguide (322) is incorporated, a wavelength selective means (324), and a movable mirror (327). The wavelength selective means (324) is fixed at the position where the light propagating the optical waveguide (322) reaches. The movable mirror (327) is arranged movably between the first position where the light propagating the optical waveguide (322) reaches and the second position which is deviated from the optical waveguide (322). With this configuration, the wavelength selective device can be obtained in a smaller structure. COPYRIGHT: (C)2006,JPO&NCIPI |
