Abstract
Spatial light modulators (SLMs) play a key role in the architecture of optical processing systems. The concept of using photorefractive crystals for SLMs (incoherent-to-coherent conversion) has been successfully demonstrated in a variety of materials and in a variety of ways. Bismuth silicon oxide crystals have been used to convert an incoherent image into a coherent image via four-wave mixing, which used three input waves in a phase conjugate geometry.1 Several devices have been demonstrated which require only two input plane waves.
