摘要：
A mirror which reflects input light from a lens which focuses light emitted from a VIPA, and returns the light to the lens is constituted as a multi-faced mirror including multiple reflection surfaces in the traveling direction of the input light which individually reflect light with a different wavelength, and have a different shape. As a result, an apparatus which has a small optical loss, and generates a different wavelength dispersion depending on a channel signal wavelength of a WDM signal.
