Abstract:

This grant explored the possible use of ferroelectric liquid crystals FLCs in the reamization of photonic switching fabrics. Problems addressed included device fabrication, switch architectures, and switch performance. Experimental versions of most architectures were constructed. The aim of the contract was to develop techniques for using ferroelectric liquid crystals FLCs for novel photonic switching architectures. Initial work was devoted to mastering the technology of making FLC polarization rotation shutters, which formed the basis for the switching architecture work to follow. Much of this work was performed using the facilities of Stanfords Center for Integrated Systems. We were able to build such shutters with respectable properties, including reasonable uniformity, an insertion losses of the order X dB and extinction ratios of the order of Y db. Switching speeds observed were the order of ZZZ. Having mastered the basic shutter technology, we moved on to employing such shutters in novel architectures.
