Abstract: An optical waveguide-type wavelength domain switch includes a waveguide-type multi/demultiplexing device laminate comprising three or more laminated waveguide-type multi/demultiplexing devices, a lens system positioned on a demultiplex side of the waveguide-type multi/demultiplexing device laminate, and a reflective optical phase-modulating cell positioned on an opposite side of the waveguide-type multi/demultiplexing device laminate to the lens system. The lens system includes a lens alignment composed of plural lenses in one-to-one correspondence with the waveguide-type multi/demultiplexing devices and having a light-collecting or collimating function in the lens-aligning direction, an image-magnifying optical system having an N:1 (N>1) image-magnifying function arranged on the optical phase-modulating cell side of the lens alignment, an f-f lens (Y) arranged on the optical phase-modulating cell side of the image-magnifying optical system, and having a light-collecting or collimating function in the same direction as the lens-aligning direction of the lens alignment, and an f-f lens (X) having a light-collecting or collimating function in a perpendicular direction to the lens-aligning direction of the lens alignment.
