Seminar Report on Optical Computing Technology

Introduction to Seminar Topic on Optical Computing Technology:

It is the advanced technology that uses light in place of current. It means that light is used to perform the operation on the computer instead of current. This technology will work better then electric current because light can travel faster than electric current this is turn will produce the result faster and better. For light transmission it might use infrared or photon to perform the operations. This technology was introduced in 1980s but it is not implemented till yet. It is under construction and various researches are going on this work. To implement this technology we need various input and output devices like processors, optical memory, electronics gates and switched and transistors.

Optical computer uses photons for operations, photons are nothing just the electromagnetic energy or we can say that unit of electricity. The transistor used in the computer can be of various types like Laser, Plasmon. Laser transistors are those which uses electrode that control the current in the devices. Plasmon transistorsare light based.

Memories used in the optical computers are holographic memory. It also said that it is 3-D memory. It removes the limitations of magnetic and optical memories have. It has better capacity than them. It has the capability to read millions of bits and read at the same time.

Advantages;they don’t have the problem of interference. Problems like electric short circuit is no more. Rate of transmission loss is very less. It provides large bandwidth so speed will be better than normal computer. They will very easy to use than normal computer.

Disadvantages: still such types of computers are not developed. They are not easy to fabricate such computers. The devices used in these computers are not affordable. New and advanced software are needed to be developed for them.
