Abstract
According to various embodiments, an optoelectronic computer architecture is described herein for use as a convolutional neural network. The optoelectronic computer architecture includes a four-focal length (4F) optical subsystem that utilizes metasurfaces and lenses in conjunction with a digital electronic subsystem. Digital-to-analog converters and analog-to-digital converters are used to interface the optical subsystem and the digital subsystem. Various 4F lens and metasurface configurations are described herein, including various folded 4F lens configurations.
