IDF Annual General Meeting held recently introduced the latest Intel product development. Congress, IntelCEO Paul Otellini and CT O JustinRattner speeches were made, Intel partners on stage some of the theories. In the fall conference, Intel will focus on the future direction of the company, including Intel's silicon photonics years of painstaking research technology!
 Present, the computer system itself, or "power" led the world. With the transistor chip integration of the raise, the work frequency of the acceleration of the increase in data bandwidth and other factors, "electricity" began increasingly face more challenges: the chip leakage current caused by the sudden increase in heat, the metal chip wire transfer can not meet more Electronic Signal the need ... ... all of which limits the integration, working frequency, data bus bandwidth, etc. to further improve, which further enhance the performance of computer serious bottleneck. Intel's silicon photonics further studied the structure and concept, it seems to find a new model, Intel in the IDF again preached silicon photonics is the use of silicon light transmission.
Silicon can be translucent? Yes. Current "call" sub-computer chips are cut off from the wafer of silicon, with natural light exposure is through, but the; no matter what kind of silicon, visible and ultraviolet light can not penetrate; but Silicon IR Is transparent, and a small loss. Advantage of silicon is very transparent, we can be made into a small device that allows light in silicon can be within a small turning away low cost, and we can do a variety of devices.
, Of course, the shortcomings of silicon is "no light, and its very low photoelectric effect, and can not detect light. Intel current research focus on: the light source, light in the chip how to conduction problems, how to light modulation and optical detection, as well as how to use the mechanical properties of silicon will be combined with optical problems. Intel's integrated kind of new technology will soon enter the trial phase, after IDF, we have to see At this point, the Intel display at the IDF HybridLaser technology-based manufacturing equipment. It is clear that we can see that the final silicon actually achieved by the transmission of light, while the human dream of new technology has finally been born:
Data because you can use the light Communication , So that the time can not take much of the electronic interference problems, and immediately used to connect hundreds or even tens of thousands of other core have become quite easy, because the connection between them only by a simple light transmission equipment on it. Intel said the technology can enhance the transistor about 50 times the data transmission capacity.
Intel also announced that the technology used inside the computer can have a future low-cost, high data path has the equipment, although from the formal commercialization may also need to wait five years or so, but because after a few dozens or even hundreds of hybrid silicon lasers and other silicon photonic components, has been integrated into a single silicon to. Realistically speaking, silicon photonics in the computer system or from the chip between the first Internet started. This is because the performance bottleneck of computer systems is still mainly in the Processor And peripheral chips and storage devices (such as Memory ), With both the technical implementation should be simpler. The longer term, silicon photonics technology into the processor chip may also be, as the medium is used Glass Optical fiber, or plastic optical fiber, also, or silicon material, the program has not yet determined.
Transistors of this technology can improve about 50 times the data transmission capacity
But like many new technologies, silicon photonic technology from experimental to practical also faces enormous challenges. Intel pointed out that the most serious problem is loss of relatively large: the current fiber can do 0.2db / km, silicon photonics silicon materials as corrosive to rely on us to do it Waveguide Present typical data is 0.2db / cm, signal attenuation is relatively large.
