Abstract
A neuromorphic network includes a first node configured to transmit a first optical signal and a second node configured to transmit a second optical signal. A waveguide optically connects the first node to the second node. An integrated optical synapse is located on the waveguide between the first node and the second node, the optical synapse configured to change an optical property based on the first optical signal and the second optical signal such that if a correlation between the first optical signal and the second optical signal is strong, the optical connection between the first node and the second node is increased and if the correlation between the first optical signal and the second optical signal is weak, the optical connection between the first node and the second node is decreased.
