ABSTRACT:
To provide a spatial optical modulation element having a long life free from a deterioration of optical modulation characteristics even if a high power laser beam with an ultra-short pulse is used as a modulation drive light. A spatial optical modulation element1wherein disposed between a prism2and an optical functional material layer3made of an optical functional material with the refractive index changeable by light irradiation, is a low refractive index layer4made of a transparent material with a refractive index lower than the refractive index of the dielectric. A spatial optical modulation method characterized in that using such a spatial optical modulation element1, at the interface between the prism and the low refractive index layer, reflection of a to-be-modulated light5entering through the prism, is controlled by a modulation drive light6.
