An optical logic system is being developed to test the packaging and operation of free space optical logic systems. It uses symmetric-self-electro-optic effect devices as the logic elements and vertical cavity surface emitting lasers (VCSELs) to provide the optical inputs. This paper discusses the issues involved with incorporating the VCSEL array into the system. Issues that are investigated include beam combining, electrical drive, and VCSEL polarization. We find that current experimental devices are appropriate for early system experiments although issues such a multimode operation and the resulting current dependent polarization need to be addressed for practical systems.
