Abstract
Spatial light modulators produce beams with a desired phase pattern, which directly affects the beam’s power spatial distribution. We demonstrate an approach for creating holographic spatial light modulators, which are permanently recorded in a photosensitive glass and do not require electric power in order to operate. The essence of the approach is that by means of holographic recording, an arbitrary phase pattern is encoded into a transmitting volume Bragg grating. Upon Bragg reconstruction, the phase pattern is reconstructed in the diffracted beam. These spatial light modulators are tunable and could be achromatic in broad spectral range.
