  11. 11. An Optical Computer Powered by Germanium Laser
  12. 12. GERMANIUM LASER
  13. 13. Concept of Picosecond BY NASA Computers used to work in millisecond(1,000ths), then moved up to microseconds(millionths),and now are approaching nanoseconds(billionths) for logic operations and PICOSECOND(TRILLIONTHS) for the switches and gates in the chip.
  14. 14. ADVANTAGES . . . . .
  15. 15. Optical Computing using a coherent source is simple to compute and understand, but it has many drawbacks like any imperfections or dust on the Optical Components will create unwanted interference pattern due to scattering effects. DRAWBACKS
