Abstract

We have implemented parts of a multistage switching network by optically interconnecting arrays of Symmeiric Self Electro-optic Effect Devices. In an experiment completed last Spring, three 16x8 arrays of S-SEEDs, all operating as logic gates were optically connected. We are currently testing a fully interconnected switching fabric using six 32x32 S-SEED arrays. These are the latest in a series of experiments to investigate and develop this technology, and they substantially involve optomechanics. The practical realization of this technology represents a challenge to modem optomechanics due to the required precision, stability, and number of components involved. An overview of free-space photonic switching and the required experimental hardware subsystems is presented, followed by details of the optical systems to interconnect the switching device arrays and the mechanical systems which locate and position the optics and devices. The tolerancing analysis used in these systems is reviewed and comparisons between the two systems are made.
