Optical interconnect and crossbar switching networks have several applications including digital computing, communications and neuro-computing. The requirements placed on the optical devices that implement the switching networks in these applications may be quite different. In computing, for example, retrieving data from memory is a major block which limits speed at which information can be processed. Fast optical interconnects may remove this bottleneck. In communications, the channel bandwidth is a primary consideration. Interconnects that switch communication channels optically may replace optoelectronic systems if they offer low cost and moderate to high speed operation. In optical neuro-computers, the significant feature of these machines is their highly interconnected architectures. Fast switching speeds are not essential. Therefore the devices needed to build these systems require different design specifications, namely low energy dissipation which enable the fabrication of large sized networks. In this paper we will discuss the requirements placed on devices by these three system applications, and present results of a polarization-based ferroelectric liquid crystal (FLC) optical interconnection network.
