Abstract
The present invention provides an optical switch for restricting a reduction in an optical coupling efficiency to an output optical path, which comprises a first spectral unit, a second spectral unit for further spectrally diffracting a plurality of wavelength components spectrally diffracted in the first spectral unit, a plurality of movable mirrors capable of reflecting the plurality of wavelength components spectrally diffracted in the second spectral unit respectively and directing the same in different directions, and a controller for compensating for deviation angles relative to optical axes of the plurality of wavelength components spectrally diffracted in the second spectral unit through setting of angles of reflecting faces in the plurality of movable mirrors.
