Continuous Optical Associative Memory
Associative memories were the first optical neural network architecture to be1, 2 implemented. Previous optical implementations have some drawbacks such as the need for an interruption of the light beam path between the different layers of the neural network due mainly by the lack of suitable optical thresholding units. As a consequence, most of the implementations so far used detectors coupled with light sources3. This solution however may cause data bottlenecks while requiring additionnai components.
