Frequently Asked Questions -- Photonic Computing

What is Photonic Computing?
Photonic Computing is digital computing in imitation of conventional electronic computing only using laser light instead of electricity, and holograms instead of silicon computer chips.

What is "Photonic"? "Photonic" comes from "photon" which is the smallest unit of light just as an electron is the smallest unit of electricity. "Photon" comes from "photo" as in "Kodak moment!"

Why use laser light instead of electricity?
Uninhibited light travels thousands of times faster than electrons in computer chips, therefore it is capable of computing thousands of times faster than electronic computing. Therefore, light computers will compute thousand of times faster than any electronic computer can ever achieve due to the physical limitation differences between light and electricity.

What is the main economic advantages of light computers?
Faster computers sell better than slow ones. Light computers will easily out-race any possible electronic computer. Also, light computers will be made of inexpensive plastic and glass that are easy to manufacture, whereas the sand from which electronic computer chips are made requires very expensive refining.

Why do people want to buy faster light computers?
Software technologies have outstripped the ability of hardware to keep up. There exist many highly sophisticated programs that must run on today's supercomputers, and even then they run too slowly. Weather prediction, speech & speech recognition, high resolution graphic and special effects are only a few of the many applications for super-speed computers.

What is a photonic transistor?
A transistor is a switch that is turned on and off by signals from other switches. They perform logic, store information and are the work horses of digital computing. Photonic transistors use light to perform the switching functions that are performed by electronic transistors in conventional computers.

How do light beams carry digital information between photonic transistors?
Light beams are like very short radio waves. Binary (digital) information is carried like an AM radio station when the beam blinks on and off. It is carried like an FM station when the beam switches back and forth between two or more colors. Just as there are able to be many radio stations in one band, light beams can carry many independent signals.

What is "bandwidth?"
Bandwidth refers to the amount of information that can be transmitted simultaneously through a given device. An AM radio has a narrow bandwidth that allows for only a hundred or so stations. A twisted pair of copper telephone wires has difficulty carrying more than one simultaneous phone conversation. A single beam of light can carry all of the worlds telephone, television, and radio stations at the same time! Whereas a single digital electronic signal in an electronic computer can carry only one bit (on or off) at any given instant, a light beam that only uses the visible part of the spectrum can carry 35 billion independent bits at that same instant, one for each color channel.

What makes the beams blink on and off? to carry digital Just as the organization of electronic transistors produces self- controlled, self-modulating electronic computers, the organization of photonic transistors, in imitation of the electronics, produces self-modulating, self-controlled light computers.

What impact is expected on the telephone industry?
Optical fibers have been replacing copper wire for many years now. Whereas light works much better for transmitting many phone calls, each fiber has an electronic bottleneck on each end. In order to expand the functional bandwidth of a full telephone system up to the capacity of the glass fiber already installed, photonic transistors will be used to interconnect the fibers, route calls, and interconnect optical components. Each fiber will then be able to carry as many phone conversations as an entire phone company can today.

What impact is expected on the electronics industry?
Historically, the electronics industry has been in a constant state of change. Every few years, the new replaces the old. However, their manufacturing technology is now pressing the electron to its physical limits, which means that there is a physical limit on how much improvement is possible. Photonics is simply the next logical upgrade. As photonic transistor products replace electronic products, the industry will convert to the new and improved just as they have always done. It's a matter of economic survival. Many people loved the old vacuum tubes, but the industry switch to transistors anyway. s

Frequently Asked Questions -- Patents

What is a patent?
A patent is a government-granted monopoly on an invention for up to 20 years. Ownership of a patent gives its owner the legal right to control the making, selling or using of the invention.

What are patent claims?
While the specification of a patent teaches ones skilled in the art how to make and implement the invention, the claims are the legal definition of the exact processes (methods) and machines (means) that are entitled to patent protection.

How are patents enforced?
Patents are enforced in civil court. An infringement suit can be filed against anyone who uses, makes, or sells a patented device or process without the owner's permission.

Can someone make some small improvement and get a patent of their own?
Certainly. The question is, is the improvement sufficiently valuable so that someone is willing to pay to have it. Secondly, having the improvement patent does not grant the new inventor any rights over the previous one. He still cannot make, sell, or use the original without permission, no matter how good his improvement. However, the improvement must be "novel." That is it must not be available on the market or described in a printed publication. It must be new. Even if an inventor publishes an article describing it in detail, he has only one year to file his patent application. Old things cannot be patented.

Can't one find a way around a patent?
The more basic an original patent is, the more difficult it is to find some other way of doing it. If one had a patent on "nuts and bolts," someone else could patent a rivet. But if one had a patent on "fasteners," then he would own rivets too.

Don't we use patented items all the time without permission?
Not really. Most patented products are produced for sale. By purchasing the item the inventor usually grants you the right to use it. However, when Sam Morse invented the telegraph, buying telegraph equipment from him would not entitle you to send telegraph messages without his permission. Ones had to pay for each telegram...they had to pay for the use of the invention.

How can someone make, sell, or use a patented process or device?
One must gain the written permission from the owner of a patent in order to be able to make, sell, or use (see above question) a patented item. Manufacturers usually obtain a license for technology, while sales outlets usually purchase the item from licensed manufacturers, or directly from the owner.

What is a license for technology?
A license is a written contract with a patent owner that grants the licensee certain spelled-out rights in relation to patented technology. AON is making certain licenses available so that the benefits of its technology can be enjoyed by others.
