OPTOELECTRONIC MESOSCOPIC NEURAL DEVICES

A novel optoelectronic mesoscopic neural device is proposed. This devi ce operates in a neural manner, involving the electron interference an d the laser threshold characteristics. The optical output is a 2-dimen sional image, and can also be colored, if the light emitting elements are fabricated to form the picture elements in 3-colors, i.e. R, G, an d B. The electron waveguiding in the proposed device is analyzed, on t he basis of the analogy between the Schrodinger's equation and the Max well's wave equation. The nonlinear neural connection is achieved, as a result of the superposition and the interferences among electron wav es transported through different waveguides. The sizes of the critical elements of this device are estimated to be within the reach of the p resent day technology. This device exceeds the conventional VLSI neuro chips by many orders of magnitude, in the number of neurons per unit a rea, as well as in the speed of operation.
