Abstract
An interconnect system has an optical transmitter mounted on a first circuit board and an optical receiver mounted on a second circuit board. The optical receiver can be nominally aligned to receive an optical signal through free space from the optical transmitter. Further, the optical receiver includes one or more light detectors, and an optical antenna coupled to direct incident light into the one or more light detectors.
