    (Or "Optical Signal Processing") Operating on data
   represented using electromagnetic radiation, e.g. visible
   light, instead of the electrical signals used in a
   conventional electronic digital computer.

   Electronic digital computers are built from transistors.
   These form components that store data and logic gates that
   perform the low-level Boolean operations such as AND, OR
   and NOT that are the basis of all digital computation.

   The optical equivalent requires material with a non-linear
   refractive index such that light beams can interact with each
   other to perform the same Boolean operations.

   Though the photons that carry optical signals offer some
   theoretical advantages over the electrons that carry
   electronic signals, there are many practical problems that
   would have to be overcome before optical computing could
   compete in terms of cost, power and speed.
