Free-space angle-multiplexed optical interconnect network

摘要

A point-to-point optical network for interconnecting processing elements uses a two-dimensional array of chips, each of which includes a two-dimensional array of lasers that are used to target a two-dimensional array of photodetectors. A two-dimensional array of lenslets together with a spherical lens are used to focus light from a laser in the j, k position in any one of the laser arrays in any one of the chips on the particular photodetector in the j,k position in the photodetector array.
