On December 14, the United Kingdom researchers on General optic fibers for fiber laboratory to fine-tune on diameters at the nanoscale, fiber optic micro-resonators used to create a Photonic computer must, for the development of a Photonic computer opens up new ways. Related study, published in the United States on optical society journal optics letters.
Photonic computer is a light signal to digital operations, logical operations, information storage and processing of new computers, because of its speed and the amount of information stored is much larger than computers, so many countries have invested heavily in research of Photonic computer. However, in order to make real photon computer, you need to develop a light beam can be used to control another variation of the beam Optical microresonators the base component.
On micro-Resonators, most potential design is of course a long list of microring, photons blockade within the ring cyclotron, then let photons through a loop to the next ring. Longer the chain, the more information can be stored. However, even if at present the most accurate manufacturing process will still produce small flaws in the ring, cause signal fade, or even disappear completely.
Latest research leader Misha · samitesiji and colleagues using fiber inherent properties, light to fine-tune on diameters at the nanoscale, the optical fiber into a micro-resonators. They make a single fiber is very narrow, and it was placed in an upright position near a single fiber. As the two beam fiber so close, and initial fibre has been reduced to a fraction of the original size and, therefore, part of light energy conduct a so-called "quantum leap" into another fiber.
This micro-resonators of signal loss is very small, while light distance running higher than traditional methods to produce micro-resonator 2 orders of magnitude or more. Samitesiji says: "accuracy of optical fiber diameter variations of about 1% NM, as well as the highest degree of accuracy. "Also, if a sufficient number of fiber optic micro-resonators coupled together, optical pulse information can be saved within a sufficiently long time, to scientists for Photonic computing. At present, they can to 10 fiber optic micro-resonators coupled together.
Previously also experiment using fibers to do micro-resonator, but they are primarily relying on polished or melt fiber to alter its diameter, which not only cause the fibre structure is not uniform, but could not achieve nanometer scale. Latest perimeter change control approach can micro-resonator in 0.1 nanometer precision. The scientists say, can be modified on the nanoscale optical fiber diameter of benefit from the inherent properties of the fiber, so as long as the fibre produced in the same environment and are heated to the melting point below, we can achieve the same effect, which makes this technology from laboratory research to industrial manufacturing. These micro-resonators are expected to be used in the manufacture of various specialized equipment, but with the immense potential to make the application of photon in the computer and used to basic physics research.
