Abstract : A program to study vertical-cavity surface emitting lasers (VCSELs) for high speed vertical optical interconnects (vol) has been conducted jointly between Rome Laboratory and Cornell University. Lasers were designed, grown, and fabricated at Cornell University. A VCSEL measurement laboratory previously designed and built was utilized at Rome Laboratory. High quality VCSEL material was grown and VCSEL lasers were fabricated on a 4x4 array for compatibility with Rome Laboratory optical interconnect demonstration programs. A major effort was the development of techniques for diamond heat sink mounting of the VCSELs for heat removal. Tasks that were conducted toward successfully meeting this goal included development of solder technology, epitaxial diamond processing, high speed transmission line fabrication and evaluation, and the development of flip-chip mounting processes.
