Evolutionary Optimization of Layouts for High Density Free Space Optical Network Links

Electrical chip- and board-level connections are becoming more and more a bottleneck in computation. A solution to that problem could be optical connections, which allow a higher bandwidth. The usage of free space optics can avoid the problem of crosstalk and geometrical signal path crossings in systems with a high density of interconnections. The choice of appropriate design parameters, allowing the realization of such interconnections, is a complicated task. We present an evolutionary algorithm that is able to find these parameters. We describe the parallel execution of that algorithm and present optimization results.
