Laser chip

A generation of chips can produce lasers, an invention that seems so simple but may be the first step for a whole new generation of computers, the computer generation does not transmit by wire.

This technique was further developed by Intel and the Santa Barbara research team at University of California. This is considered a new way to solve the internal transmission of computers.

In a computer, data transmission, transmission and reception systems are considered traffic arteries. The problem now is the 'bottleneck' phenomenon when computers work with large amounts of data. People have used many ways to overcome this phenomenon such as increasing the amount of cache, increasing the bus . but still not losing, only systems are getting more complicated if you want to increase the internal transmission bandwidth. computer.

Therefore, the microprocessor (chip) on the semiconductor platform capable of laser emission is a solution. Instead of transmitting wires on wires, data will be delivered directly from chip to chip within the computer by laser, absolute simplicity of design, as well as bandwidth for data is immensely. The remaining work now is transceiver (tranceiver, receiver).

Laser has been used to transmit data in large distances for a long time. However, minimizing transceiver devices to the point of being able to integrate into an IC is always a challenge until recently. It is estimated that the internal data transfer rate in a laser computer will be 100 times faster than the laser data transmission through optical fibers over large distances.

Laser transceiver chips have been commercialized in recent years. The achievement of the Intel-Santa barbara team is to produce chips with optical devices using normal microprocessor machines, something that in the past seemed impossible.

A computer form is gradually being formed. Maybe computers without wires will be available by the end of this decade.
