Optical computing: introduction by the feature editors

Yao Li, Jun Tanida, Frank Tooley, Kelvin Wagner
1996 Applied Optics  
In the introduction to the 1992 feature, Jenkins et al. 6 attempted to predict the directions in which the field of optical computing would be likely to expand.  ...  They identified optical interconnection as the most promising opportunity for bringing optics into computing.  ...  Competition between electronic and optical technologies would then die out as the focus would be on complementing electronics rather than on competing with it.  ...
