Patent ID: 6858872

Claim:
An optical interconnection integrated circuit, comprising: at least two integrated circuit chips; at least one tile-shaped microelement bonded to each of the integrated circuit chips; at least one light-emitting element provided in at least one of the tile-shaped microelements, the light-emitting element emitting optical signals; and at least one light-receiving element provided in another of the at least one of the tile-shaped microelements, to detect light emitted from the light-emitting element, the light-receiving element receiving the optical signals emitted from the light-emitting element, each of the tile-shaped microelements including only one of the light-emitting elements or the light-receiving elements, and the optical signal output emitted from the light-emitting element on a first integrated circuit chip is received approximately at the same time by the light-receiving elements located on a second integrated circuit chip.
