Abstract: Utilizing the principles of wavelength-dependent evanescent wave coupling in closely-spaced optical waveguides, along with optical resonators, a method for creating a neural network out of entirely electro-optical components is discussed. Optical resonators, which can store energy as standing waves or whispering gallery modes, act as neurons. Waveguides integrated onto a chip act as dendrites or connectomes, with coupling between them simulating the analog exchange of signals in brains. Additional electro-optic controls can be utilized, such as conductive plates utilizing the electro-optic effect to change the refractive indices of the optics and coupling coefficients based on electrical signals from outside stimuli.
