Optical computer 3

There are lots of ways to make optical switches. The mechanisms I researched once upon a time (20 years ago) relied on optical gratings. Most people are familiar with the way different colors of light exit a prism at different angles, but a diffraction grating can also give this effect. When a laser beam of a single wavelength falls on a grating, the spacing of the grating interacting with the wavelength of the light causes the light to diffract off at a known angle.

Spectrometers that measure the spectrum of light sources such as stars have a precisely etched grating on a hard surface, but there are other ways to make gratings. For example, acoustic switches can set up a standing wave on an optical element and quickly turn on and off, but the time for the switch to change states isn’t any faster than the speed of sound in the material.

To get a faster operating switch, an electric field can be applied to some materials, and a grating will appear in the material (google Kerr Effect). A real application for this kind of switch is in “Q-switched” lasers that build up large pulses.

Another technique that might hold promise for optical computers would be to actually create the grating from the laser light beams themselves. When two beams cross in a crystal, the electric field of the light itself can interact with the matter to create a periodic pattern, a grating. A third beam will either pass through or deflect depending on the presence or absence of the first two beams. We tested several materials measuring state change, switch life, etc. Some crystals actually have a significant time before the field relaxes, which could serve as kind of “memory,” and the data density of storing 3 dimensional holograms in even a 1 cm^3 crystal is immense.

I haven’t revisited the topic but a few times in the last two decades, but all of the elements for a working, purely optical computer were physically possible (if not practical) for a while now.

the all laser approach sounds neat , a phonic cell that can store and return data… if the “dwell time” could be around the dwell of ram…

The dwell time of RAM and laser could assist in other applications too. It is just so like so neat. Really.

That looks fun!

QuadTracktorsorus Welds?

Apparently it’s a machine that if I remember correctly serves as a mini crane. Fabulous little device. But as I try not to hijack topics, back to topic…something topic like related. Oh yeah…chips! In computers. They are sure progressing. With light in the current time too, to make something optical.

What is a cognitive chip? The latest SyNAPSE chip, introduced on August 7, 2014, has the potential to transform mobility by spurring innovation around an entirely new class of applications with sensory capabilities at incredibly low power levels. This is enabled by an revolutionary new technology design inspired by the human brain. IBM built a new chip with a brain-inspired computer architecture powered by an unprecedented 1 million neurons and 256 million synapses. It is the largest chip IBM has ever built at 5.4 billion transistors, and has an on-chip network of 4,096 neurosynaptic cores. Yet, it only consumes 70mW during real-time operation — orders of magnitude less energy than traditional chips. As part of a complete cognitive hardware and software ecosystem, this technology opens new computing frontiers for distributed sensor and supercomputing applications.

Symphony of nanoplasmonic and optical resonators produces laser-like light...

“We have made optical systems at the microscopic scale that amplify light and produce ultra-narrowband spectral output,” explained J. Gary Eden, a professor of electrical and computer engineering (ECE) at Illinois. "These new optical amplifiers are well-suited for routing optical power on a chip containing both electronic and optical components.

Most of today’s electronic products consist of traditional made parts. Plastic molded housings containing PCB’s with soldered THT and SMT components. In many cases even the design of a product is based on the electronics that should fit inside! Shouldn’t it be the other way around? Shouldn’t the electronics be a part of the design based on ergonomics and aesthetics?

How about static memory a la quantum coherence? When photons are absorbed by atoms the electron/s move to higher shelves or energy states. That energy state tends to degrade and a photon is given off. This is uncontrollably probabilistic.

I don’t think your actually talking about a photonic computer. I think your talking about fiber optic PCBs, which is pretty damned cool just the same.

On the other hand; if you have solved the quantum coherence problem then please contact Geordie Rose. He’ll make you friggin’ rich.

No, what I am thinking,

Send data laser rgb via 12 outputs
Like up left,
Up left back,

This way a networkof stackable cubes, on top of a mat, could be a computer,

Think fiber optic lego pc, and each part can be a differing piece, but all are networking nodes,

So, HP photonic interconnects, built in 3d, and laser emmiters, and a device, in each cube.

Rice grain-sized laser helps build the first quantum computer

Princeton researchers demonstrated a novel type of microwave laser – called a maser – so small that’s the size of a grain of rice. The laser is powered by individual electrons that tunnel through artificial atoms known as quantum dots.

Creating optical cables out of thin air

ok the deal is sealed, now a optical computer can be distributed across a room,

remember my 3d logic node system?

it just got real…

now I see

a power beam,
reciever beam
brodcast beam

this way, a hub, can power, feed data and recieve error data using a mems array to feed an array of chips, and then recieve feedback data.

if a chip is powered without wires, sends data without wire, and recieves data without wires, a true 100% scalable architecture can be achieved.

Ryzen Up: AMD to 3D Stack DRAM and SRAM on Processors

[Ace_Dragon]

It’s an interesting take on the problem of trying to keep the upward trend in performance, but what does this have to do with optics?

This could’ve been posted as a new thread rather than digging down 4 years to bump this one.

I said that the future of computing is small nodes with self contained ram/proccessor

I think one could have ‘states’ and complex logic in these self contained cells,

so that depending on the problems being solved the architecture can change.

this is a step in that direction, however it’s not a grid sending / receiving light yet

(think of GLSL nodes that instead are real hardware and switch states to perform specific operations very fast and data flows both ways on the node graph.)

Excitons pave the way to more efficient electronics

this is cool,

one may be able to manipulate a laser en-route without absorbing it

If its R B G , then its not like current computer, a binary system / off & one state , but a tertiary system. Just a thought

binary 2 ** 8 = 256 mb ram
tertiary 3 ** 9 = 19 683 mb ram
