To make a wavelength selection optical cross-connect device compact while reducing the mounting surface area and power consumption, without using a large number of movable components such as wavelength selection switches or MEMS.
Wavelength multiplex light of first through M-th channels is applied to a wavelength selection optical cross-connect device, dispersed by a wavelength dispersion element 14, and transmitted to a spatial modulation element 15. The light incident to an arbitrary region of the spatial modulation element 15 is emitted to an arbitrary region for output under control of a controller 17 before entering a second spatial modulation element 16. The second spatial modulation element 16 makes the light from N strip-shaped regions enter a wavelength synthetic element thus synthesizing the wavelengths of respective beams before being output from a plurality of ports. Consequently, wavelength multiplex light of the M channel input to input routes Rin1-RinM are output from output routes Rout1-RoutN while selecting the path for each wavelength of each channel.
