  • Continuous-time optical neural network process
    Patent number: 5132835
    Abstract: An all-optical, continuous-time, recurrent neural network is disclosed which is capable of executing a broad class of energy-minimizing neural net algorithms. The network is a resonator which contains a saturable, two-beam amplifier; two volume holograms; and a linear, two-beam amplifier. The saturable amplifier permits, through the use of a spatially patterned signal beam, the realization of a two-dimensional optical neuron array; the two volume holograms provide adaptive, global network interconnectivity; and the linear amplifier supplies sufficient resonator gain to permit convergent operation of the network.
    Type: Grant
    Filed: August 3, 1990
    Date of Patent: July 21, 1992
    Assignee: Northrop Corporation
    Inventors: Harold M. Stoll, Li-Shing Lee
