Two architectural approaches have dominated the field of optical computing. The first approach uses integrated optics to connect logic gates in arbitrary configurations similar to a conventional computer. An optical computer built with this approach competes directly with a conventional computer. The approach is successful when it results in a computer which is more powerful and can be made more cheaply. The second approach makes use of two dimensional arrays of logic devices interconnected in free space. This approach cannot provide arbitrary connections as do integrated optics but the density and the bandwidth of free space interconnects can be much larger than what is offered by conventional interconnects. A more fundamental advantage of optical interconnects is that lower energy communications appear to be possible than with electronic interconnects.
