Abstract
An optical device includes: wavelength selection elements; an optical switch that switches a propagation path of input light that is from an input port such that the input light propagates to one designated wavelength selection element among the wavelength selection elements; and a separation element disposed in the propagation path of the input light between the input port and the wavelength selection elements and that separates the input light into wavelength components.
