PROBLEM TO BE SOLVED: To provide an optical ADM device which is capable of suppressing that the device becomes large. SOLUTION: In the optical ADM device, a first channel waveguide section 10, a first slab waveguide section 20, an array waveguide section 30, a second slab waveguide section 40 and a second channel waveguide section 50 for wavelength separation and synthesis are formed on a substrate 2. And also, a switch section 60 is disposed on a substrate 2. The switch section 60 has movable mirrors 61. The movable mirrors 61 are freely movable in an advance direction and retreat direction with respect to the optical paths in the second channel waveguides 511 to 51N for wavelength separation and second channel waveguides 521 to 52N for wavelength synthesis. The movable mirrors 61 is disposed on the substrate 2 in such a manner that the movable mirrors 61 are made freely movable in the advance direction and retreat direction with respect to groove parts 3 of the positions corresponding to respective intersection parts. |
