Abstract
A free-space optical interconnect architecture is presented that is tolerant of the lateral misalignment of integrated circuit boards in multi-chip module packages. Each transmitter has a different wavelength and correspondingly sensitive detector. The transmitted beams are spread such that the beams' half angles are slightly greater than the maximum expected misalignment.
