SINGLE-LAYER OPTICAL POINT-TO-POINT NETWORK

摘要

In a multi-chip module (MCM), first and second optical waveguides convey optical signals among integrated circuits. The first and second optical waveguides may be implemented in a first layer or plane on a substrate. Moreover, bridge chips in a second plane may be used to couple the optical signals between the first or second optical waveguides and the integrated circuits. By using a single layer for optical routing, the MCM may provide a point-to-point network among the integrated circuits without optical-waveguide crossing.
