Photorefractive Ring Resonator Optical Associative Memory

摘要

Optical associative memories (OAM's) can recall stored images from partial ornoise degraded input images. One proposed way to implement an OAM is to store the desired images as holograms in a ring resonator geometry. If certain conditions are met, these images can be retrieved from partial or noisy inputs. The separate components of this scheme were investigated in several small experiments. Limitations and drawbacks of the ring resonator approach were discovered, and the desired associative memory system performance was not achieved.
