Research output: Contribution to journalArticlepeer-review


We describe various image bearing oscillations originating in one, or two coupled photorefractive crystals, which can support phase and amplitude modulation as well as multimode fibers. This includes a first report to our knowledge of the operation of the Double Phase Conjugate Mirror. This four-wave mixing device can be pumped simultaneously by image bearing beams originating from the same or different lasers, and couples these two beams into each other. These configurations have potential applications in real-time image processing.
