New Super Computer

Researchers have created a new type of optical device that is small enough to contain millions of data on a single computer chip that could eventually create an information processing system is faster and stronger, while creating a super computer.
"Positive optical diode" is made of two thin silicon rings measuring 10 microns in diameter or thick-tenth of a human hair.

Unlike other optical diode, the diode does not need outside help to transmit the signal and can be easily integrated into computer chips.
Diode is capable of "transmitting nonresiprokal" which means transmits a signal through only one direction so that makes it capable of processing information, said Minghao Qi, professor of electrical and computer engineering at Purdue University.
"Transmission in one direction is the most fundamental part of a logic circuit, so that the diodes we opened the door to optical information processing," said Qi, who works in a team with Andrew Weiner, who is also a professor of electrical and computer engineering at the same university.
Diodes is described in a paper published online on December 22 in the journal Science. The paper was written by the students S1 Li Fan, Jian Wang, Leo Varghese, Hao Shen and Ben Niu.
Although fiberoptik cables are important in transmitting large amounts of data from around the world, but instead slowed information processing and data vulnerable to cyber attacks when the optical signal must be translated into electronic signals for use in computers, and vice versa.
"Translating this requires expensive devices," said Wang. "The more you have to do is place the fiber was directly into the computer with no need of translation, and then you get a lot bandwidhth and security (internet)."
Electronic diodes consist of important junctions in transistors and integrated circuits that assist in turning on and off as well as process information.
The new optical diodes are kamptibel with industry and the manufacturing process to semikondukter metaloksida complementary (complementary metal-oxide-Semiconductors or CMOS) are used to produce computer chips, said Fan.
"Diode-diode is very solid and they have other attributes that make it attractive as a component of the potential for photonic information processing chips in the future," he said.
The new optical diodes can speed up and make the processing of information becomes more secure with no need anymore translations.
The devices are almost ready lent can also create a supercomputer that is much faster and more powerful by connecting it to any number of processors simultaneously.
"The biggest factor that limits supercomputers today are speed and bandwidth of communication between each of the superchip in the system," says Varghese.
"Our optical diodes can be a component role in optical interconnect system that can eliminate such obstacles."
Infra-red rays from the laser at a wavelength of communications transmitted over a single optical fiber and guided by the so-called microstructure waveguides. Then it is passed sequentially through two rings of silicon and run the nonlinear interaction while in the small ring.
Depending on where the beam entered the ring to the first time, infra-red rays will be melalaui either scattered in the forward direction or backward direction, thus creating a one-way transmission.
Rings can be adjusted by heating through a "micro-heater" that change the wavelength at which the ring is transmitted so that makes it able to overcome the overall frequency range.
