Transcript of Optical Computing
Optical Computer: "a device that uses photons, thin films, crystals, and optical fibers to perform digital computations"
Optical Computing is needed today due to peripheral devices are becoming much more demanding and are outrunning their electrical wiring.
Uses In the Field
Impact and Opportunities for End Users
Will replace electrons, which travel along copper wires, with photons. Photons are the fastest thing in the universe.

Makes use of photons of different colors of light to send and receive signals
Plans for the future..
Drawbacks for End Users
The components needed to convert to optical are very expensive and not ideal for personal computers.
Benefits of Optical Computing
Examples of Optical Computing being used:
Light Peak by Intel - gives the ordinary PC the ability to connect with other devices using high speed optical cables at 10 gigabits per second (20x faster than a standard USP cable)
The first optical transistors were developed in the 1980s
Predicted by experts:
2-5 years: optical connections will enter the computer, this will connect one circuit board to another.
6-10 years: optical connections between Chip-to-Chip.
15+ years: An all-optical computer is the future goal, but many scientist have mixed predictions as to whether this will ever be possible.
Optical computing could process information at speeds that make even a supercomputer look slow and sluggish.
IBM is using optical interconnects to make supercomputers run faster. They are mounting fiber-optic cables straight into chips that direct the traffic between the supercomputer's multiple processors.

Photons are ideal for transmitting information over long distances . They travel through optical fibers and rarely get lost or interfere with one another.
Compact, lightweight, low-powered electronics, and a growing demand for greater data throughput and bandwidth is driving the use of optical computing in military and aerospace applications.

Over 60-years of research in the field of Optical Computing.
Enthusiasm in the sixties due to introduction of the Joint Transform Correlator & the Laser.

Similar application to Spectral lines for elements. Color photons that are given off, identify a specific atom and element
(A photon is a quantum of light or other electromagnetic radiation.)
Any imperfections, such as dust, can cause interference
High processing speed
that increases data rate transmission
, no fans needed for cooling
on parts due to lack of need for as many moving parts
Take a few minutes to watch...

Follow link to article about Military application of optical computing. Since it is lighter weight and faster processing, military adopted for its planes.
Outcome was successful
Electronic Computing will soon be unable to keep up with society, but Optical Computing will give the speed that is needed.

Explanation of Optical Computing
Laser to compute simultaneously

Incompatibility with modern PC architectural structure
After the laser was introduced, rapid expansion in the field.
