High-order associative memories are of interest because of their potentially large storage capacity. We describe an optoelectronic implementation of a second-order, or quadratic, associative memory. The two-layer network is based on an inner-product representation, which allows for a compact implementation using an optical chip design. Experimental results obtained from our system are discussed.
