Abstract
An optical transmission device includes: a spectral element configured to disperse an incident light beam in a first direction according to a wavelength of the incident light beam; a mirror array configured by a plurality of mirrors, each mirror having a reflective surface in which a reflection angle is adjustable and to which the incident light beam dispersed in the first direction is incident, the reflective surface being arranged on a plane formed by the first direction and a second direction orthogonal to the first direction; a plurality of ports arranged in the second direction; and a controller configured to adjust the reflection angle, so that a light beam reflected at the reflective surface is outputted to the port according to a region segmented in the second direction in the mirror array, the dispersed incident light beam that has a specified wavelength band being incident to the reflective surface.
