Abstract
An integrated optical circuit for holographic information processing is disclosed. The optical circuit comprises a photorefractive medium and two transmitter arrays. The transmitter arrays are adapted for locally changing the refractive index of the photorefractive medium for holographic encoding of the information in a working plane of the photorefractive medium by transmitting light via optical paths into the photorefractive medium such that an interference pattern is generated in the working plane. The optical paths and the working plane are arranged in a single optical plane.
