摘要：
A wavelength dispersion compensation device includes an etalon 100 having a slab shape. Reflective films are formed on each side of the etalon 100. The reflective films respectively have predetermined reflectance. Reflectance of one of the reflective films differs according to a light incident angle by using a portion of light within a wavelength range to be used with which a filter characteristic in which transmittance rapidly changes is obtained.
