Can computer work using light instead of chips. |
We know electical Chips in computer uses electrons for computations.
Can that be replaced by Light.
Electrons flow only a few 100 m/s while light travels 100,000 times
faster than electron.
If circuits are made using light even 10 times big Chip will work
10,000 times faster.
Imagine Laptops/ Desktops working 10,000 times faster than they are
today.

Ah! uFO.
Yes. Light is the fastest *"measurement"* and therefore our fastest

However, as anything requires an energy, the solar energy along that matter
would be supposed to do the job, a definitely as a matter a fact.

I do not know anything about the subject but i always thought that the
binary switch circuit do not use the full calculation potential. A
multiple state machine where different light spectrums mixed to make
calculatsions could be infinitly more effective.
Let each spectrum have a range representing a bit value, i do not
think there would be any problem making a 8,16 or even 32 spectrum
machine to make the actual basic operations + - would not present any
problem the problem would of course be storing the results and one
probably would have to use conventional memory technologies.
But then again why not starting making modular circuit just solving a
simple addition task to begin with. Let binary integer/word values be
optically translated into a frequensy spectrum matrix that somehow
perform addition or other calculations by blending two or more
spectras and instantly piping out the new spectra from the matrix and
by using optics read and translate the value into a binary value by
it's frequensy.

Oh we do.
Ruby synthuby ,,,tube 12 inch long is more space to store information
code then all the pc's comibined.
But the tube is just te memory ,'
The laser pc is chips stacked between photocells and form a tube
inside the ruby tube.
and the laser can hit any cell of a grid any point inside the tube
one pixel at a time.
Information went boath ways threw the mirrer coated ruby back threw the
chips.
the outside of the ruby tube is chroamed.
the laser is a laser in the ruby tube and sends the beam back into
another pixel chip.
The 1 beam went threw the chip effectng it then into memory having
deflected there from chip and back put memory tube into another point on
the chip tube.
Like the inside tube was watching color laser tv.

Interestingly, I had the same "brilliant idea" when I was in high
school. I had even worked out some of the things you leave as
"somehow". My high school teacher sent me to the local university's
computer science department for the summer to work on the idea with
some people who know what they're talking about. Very quickly I
learned how unformed this "brilliant idea" was, and how much further
along people were on the effort, and how hard it was to solve even the
littlest hurdle. Kept me from becoming a computer scientist. Went into
something much more frustrating instead. :>)

If i however thought that i did succeed i probably sent the solution
to someone. But then again maybe it was not a possible way to go.
Because then we all would have heard about it now, if it did not end

if i made any progress. But since i beleive easiest way of making

tried to use the fact that output from a cathode ray works with RGB,

Nah maybe no good idea to let the ray sweep would be slow better

Electrons flow only a few 100 m/s while light travels 100,000 times
faster than electron.
But the electric signal in a conductor is much much faster, close to c.
Think of the electrons in the conductor as marbles in a tube.
If you push on one side, the marble on the other end will move too,
almost immediately, while the first marble only moved a fraction of its size.
So your argument is void.
It is also void because to 'create a light source' and a 'light detector'
you will need electronics, lots of it.
Photo diodes are by nature slow.
One way would be to be able to make light controlled light switches.
And light powered too?
Show me you light NAND gate, and its speed.
Compare it to for example a Josephson switch and its speed.

Another underlying assumption in our discussions of modern computers
is that they are electronic. But now scientists are developing a new
medium for logical manipulations: light. The many advantages to
running a computer on light are currently being explored by numerous
laboratories worldwide. Light waves can cross, so that different
channels of information pass through each other rather than short
circuit, as in an electronic computer. The use of light in
communicating with and between processors will pave the way to
completely new classes of computer architecture. Imagine the
difference to the traffic flow in a city such as London or New York if
all the cars could pass through one another.
Optics avoids problems of "crosstalk" between wires at high-signal
frequencies. It also circumvents signal loss at high frequencies. Vast
numbers of interconnections can be spun and broken in complex
topologies. These advantages outweigh even the best known benefit of
using light: that photons traveling in vacua move about one thousand
times faster than electronic signals propagate in the conducting and
semiconducting materials used in microprocessors. This means that
winks of light can be processed more quickly than electrical signals.
Light thus offers the promise of machines that would be more versatile
than the most powerful computers in use today. Optical fibers are
already being used to carry telecommunications data across oceans and
continents, lasers help to store information on compact discs, and
there are optical circuits that can carry out computing, though
currently a mixture called optoelectronics, where optics is used for
interconnection and electronics performs the logic, looks more
promising. Indeed, no computer is complete without one crucial piece
of optoelectronics-its display.
The properties of light can be exploited to carry out logical
operations for computing. Light can be thought of as consisting of
particles (photons) or waves. This dual nature can be described by
quantum mechanics, as we will discuss later. For the moment, it is
convenient to portray light purely as an electromagnetic wave. When a
light wave passes from one medium to another, it changes direction.
One can imagine that the equivalent of a Boolean logic gate could be
achieved by bending a pencil beam of red laser light with a simple
prism: "on" might correspond to the beam forming a spot on the wall;
"off" might be the beam deflected on to the floor. Manipulating light
beams with prisms would be a cumbersome affair but more subtle methods
are at hand.
A team of British scientists who relocated to the United States
created the world's first digital optical processor, the forerunner of
computers based on light. David Miller, Michael Prise, Nicholas Craft,
and Frank Tooley did their pioneering work while at Heriot-Watt
University in Edinburgh. In 1990, with support from twelve scientists
at AT&T's Bell Laboratories in New Jersey, the team developed a simple
optical counter that can be upgraded to make an optical adder or
multiplier. Although it was too small to be of any practical use, it
did communicate all of its information internally using only light
beams.
Like conventional electronics, optical processors require simple
switches. The switch used in the Bell Laboratories device was called
the S-Seed (symmetric self electro-optic effect device) and changes
its refractive index and absorption properties to turn laser beams on
and off. In their first optical processor, four layers of units, each
consisting of thirty-two S-Seeds, "talked" to each other using beams
of near infrared laser light. The four arrays of S-Seeds were
separated by lenses, mirrors, and masks that served the same function
as wiring in a normal computer. The processor carries out calculations
by alternating switches from on to off, and vice versa. Extensive
follow-up work on this first processor has yielded experimental
processors with a light show that would put a high-tech discotheque to
shame: 60,000 light beams interconnecting 12,000 devices of a more
advanced type, called a FET-SEED.
Conventional semiconductor diode lasers employed for optical
information storage and communication are too big to be useful in
optical computers. Complementing the work on processors, dramatic
advances have already been achieved in the manufacture of miniaturized
lasers. Individual neighboring lasers within the array can also be
made to emit light at different wavelengths, offering technologists
the possibility of sending multiple signals along optical fibers
simultaneously. And microlaser arrays can also be switched on and off
with pulses of light, a feature that will prove useful in constructing
parallel optical computers. These arrays, integrated optoelectronics,
and optical processors will very likely be at the heart of future
computers. According to David Miller of AT&T Bell Laboratories, "The
difficulties in design of current electronic computers are so
daunting, and the reality of computational problems we cannot solve so
striking, that one would be a pessimist indeed not to believe in a
future for optics in digital computing."

I once played against a chess champion, he offered a draw.
Asked why (I am no good chess player) he replied the prospect of
him undergoing brain configuration changes was not something
he set out to do, he wanted to stay inside his box.
You can play Chess with Computer as well as Human opponents here.
And your Games are Recorded.http://www.GetClub.com/Chess.html
I played GNU chess a couple of times, then I looked up the source code.
Is that cheating? Anyways playing it made me sleepy, I stopped playing
against machines.
I prefer to play _with_ machines.
An inmate sentenced to solitary confinement on the desert planet ceres-
XIV receives a feminine robot to keep him company. At first, he
detests her, rejecting her as a mere machine. However, when he sees
she is capable of crying, in time he learns to love her.
When a ship brings the news that he has been pardoned after a review
of past cases and that he can go home immediately, he is
delighted...until he learns that there is only room for 15 pounds of
luggage, far too little for his robot. The man frantically tries to
find some way to take her with him, but there is no solution. When he
decides to stay on ceres-XIV instead, the captain of the ship finally
shoots it in the face and takes him aboard, assuring him he will be
leaving behind loneliness.
