ABSTRACT:
A chirp compensation dielectric multilayer film mirror (10) reflects an incident light in a predetermined wavelength range and has group delay characteristics that prevent at least one of the dielectric multilayer film mirror (10) and a light transmission portion from applying a phase disturbance to an incident light within the predetermined wavelength range. Therefore, all the wavelength components of the incident light in the predetermined wavelength range are reflected by the chirp compensation dielectric multilayer-film mirror (10), and no additional undesired phase disturbance occurs by the dielectric multilayer film mirror (10) and the light transmission portion. Accordingly, a spatial light modulator (1) enables a desired modulation only by a liquid crystal layer without giving an additional undesired phase disturbance to an output light.
