Fastest Silicon Chip

Now the day comes when Intel launches its fastest chip that is totally made of silicon . The main aim behind the launching of this chip is to made a chip that can encode 200 gigabits of data per second on a beam of light. As all we know the fastest chips that are used today in fastest optical networks operate at speeds of 100 gigabits per second. All these 100 gigabits chips are made from non-silicon materials so that they have some limitations while in the case of Intel's chip it doesn't, these intel chips can scale to faster speeds as less expensively as can those are not made from silicon.

The main reason behind the use of silicon for the manufacturing of chips is that its optical properties are inferior to those of other semiconductors and also it doesn't produce, detect, and manipulate photons as well as materials such as indium phosphide and gallium arsenide.This new Intel test chip splits an incoming beam of light into eight channels. Within each channel is a modulator, a device that encodes data onto light. After the beams are encoded with data, they are recombined. In the tests, each modulator ran at a rate of 25 gigabits per second, and each performed nearly identically.As it is already proved by Intel researchers that silicon could be used to build a one-gigabit-per-second modulator and in 2005, the team boosted the speed to 10 gigabits per second.
