  1. Optical Computing

  2. Objectives • Definition of Optical computing • Advantages of Optical computing • Optical components for binary digital computer • Misconceptions, challenges and prospects • Photonic logic • References

  3. Optical Computing • Optical computing is a computing technology in the research and theory stage. The idea would be to make a computer that relies entirely on light (photons) instead of electricity (electrons) to do computing.

  4. Advantages of Optical computing • Higher performance -metallic wires reduce the transmission speed. -nothing is faster than the speed of light. • Higher parallelism -data paths can cross without interference. -increase the amount of data which is sent through bus systems and and computed in the CPU at each time.

  5. Advantages of Optical computing • Less consumption -computers consume a lot of energy. • Less heat is released -optical computers function with the use of lasers. • Less noise -the noise factor is reduced significantly. • Reduced loss in communication -transmitted through electric wires or radio frequency.

  6. Optical components for binary digital components • Fundamental building block of modern electronics • computers -transistors -Non-linear refractive index -Logic gates Controversy There are ongoing disagreements among researchers with regard to the future capabilities of optical computers

  7. Misconceptions, challenges and prospects • Shot noise • Thermal noise • Informational theory • Nonlinear • Electromagnetic wave

  8. Photonic Logic Realization of a Photonic Controlled-NOT Gate for use in Quantum Computing • Light and logical gate • Photonic logic is the use of photons • Switching is obtained using nonlinear optical effects

  9. Resonators • are especially useful in photonic logic, since they allow a build-up of energy from constructive interference, thus enhancing optical nonlinear effects. include photonic logic at a molecular level using photoluminescent chemicals.
