We describe the configuration, fabrication, and functions of an optical neuron device which is capable of performing both summation and threshold operations in optics. We constructed an alloptical neural network using these devices, a lenslet array for forming optical interconnections between neurons, ...
Here, we demonstrate a fully functioning all-optical neural network (AONN), in which linear operations are programmed by spatial light modulators and Fourier lenses, while nonlinear optical activation functions are realized in laser-cooled atoms with electromagnetically induced transparency. Because all ...
