Abstract
A wavelength-selecting optical switch device includes: an optical input/output port including a plurality of ports; an optical operation element having polarization dependence characteristics and configured to output light input from any port of the optical input/output port to any port of the optical input/output port; a condenser lens system configured to optically couple the optical input/output port with the optical operation element; an optical dispersion element configured to disperse input light in a light dispersion direction; a polarization operation element configured to output two lights having a polarization state orthogonal to each other in a direction forming an angle to each other on a plane parallel to the optical switch direction; and a polarization rotation element configured to cause polarization directions of two lights output from the polarization operation element and having a polarization state orthogonal to each other to be identical to each other.
