2. • Optical computing describes a new
technological approach for constructing
computer’s processors and other components
• An Optical Computer is
a hypothetical device
that uses visible light or
infrared beams, rather
than electric current, to
perform digital
computations

3.  Hard disk
 CPU
 Cache memory
 Main memory
 Power supply
 Screen

4. • Optical analog
• Optoelectronics
• Optical parallel digital computers
• Optical neural copmuter

5.  So to make computers faster, their components
must be smaller and there by decrease the
distance between them.
 This has resulted in the development of very large scale
integration (VLSI) technology.
 But they are limited not only by the speed of electrons in
matter but also by the increasing density of
interconnections necessary to link the electronic gates on
microchips.

6.  One of the theoretical limits on how fast a computer can
function is given by Einstein’s principle that signal cannot
propagate faster than speed of light.
 The optical computing comes as a solution of miniaturization
problem.

7.  Optical data processing have several
advantages over the electronic
 They are compact lightweight and inexpensive
 Optical data processing is faster and easier
than electronics
 Optics has a higher bandwidth capacity over
electronics
