Optical Computing-recent Trend in it

July 31st, 2010

Optical computing means performing computations, operations, storage and transmission of data using light instead of electricity.  Instead of silicon chips optical computer uses organic polymers like phthalocyanine and polydiacetylene.Optical technology promises massive upgrades in the efficiency and speed of computers, as well as significant shrinkage in their size and cost. An optical desktop computer is capable of processing data up to 1, 00,000 times faster than current models.

Advantages


Optical computing is cheaper or more powerful than conventional computers.
Within one data path several data sets can be transmitted parallel at the same time using different wavelengths or polarizations. Data paths are able to cross each other without interference.
The superior velocity of light allows extreme processing speeds.
Optical computers are said to run much faster than electronic

computers

Disadvantages  


The development of its price is still expensive
Optical components can be build small and compact but not really miniaturized
Optical computers may use a different architecture. So these programs cannot use the full optical computers
High-tech factory costs several millions up to billions of dollars to be built

Difference between Optical computing and conventional computing

Optical computing


Data paths are able to cross each other without interference
Based on two dimensions 
High performance
Bottleneck could disappear
Less heat is released
Less noise
Change the shape and layout
The distance of communication does not matter
Long-range communication is possible. the data rate is very high and there is no crosstalk
