Abstract : The goal of this project has been to develop microlenses on the back-side of Vertical-Cavity Lasers (VCLs) and use them in a free-space link. In the process, it was also realized that a simulation program was necessary to evaluate the link. The link simulator program was written in ANSI C, but interfaced with HSPICE, a commercial circuit simulation package, to allow accurate analysis of the laser driver and/or receiver circuit as well as the laser and detector parasitics. Using the program, signals can be traced as they propagate through the link. This not only provides information about the link's performance, but also about link components and their interactions. After describing the program's structure and operation, simulation results will be presented. Two students were involved in this grant. Ms Strzelecka focused on the microlenses and Mr Louderback worked on the link simulator. Ms Strezelecka will be finishing her Ph.D by early 1997 and Mr Louderback is in an earlier stage of his Ph.D work.
