ABSTRACT:
The invention uses optically active dyes or other optically active materials to perform digital data processing and logic functions on optical data. The data is carried in pulses of photons of wavelengths appropriate to interact with the optically active materials to excite or de-excite them. The use of the invention in performing various optical processing functions is described.
