Abstract

The present invention provides an apparatus and method for free-space optical communication. The apparatus includes a first board with a plurality of optoelectronic converter components mounted on the first board. The apparatus additionally includes at least one optics element optically aligned with at least one of the optoelectronic converter components, where the optics element is configured to pass light directly between free-space and the plurality of optoelectronic converter components, and electronics coupled to at least one of the plurality of optoelectronic converter component. In one embodiment, communication is achieved by providing electric signals to a plurality of lasers that are mounted on a first board, generating a plurality of optical signals with the plurality of lasers and directing the plurality of optical signals into free-space with a plurality of optics elements.
