Introduction of silicon photonics technology

These installation in the data center server ugly chip, has been in continuous development, chip optical technology is also in constant progress. Silicon photonics technology, the use of silicon semiconductor as the optical signal medium, the transmission of digital signal than the traditional electronic semiconductor device much faster.
Silicon photonics technology involves several core components. First, the laser is the heart of any optical device. The present laser using silicon and Indium Phosphate to produce the same infrared laser. Then the photons need to be modulated, and the light breaks down to form a light pulse. Optical waveguides and other interconnecting devices move from one place to another. In addition, because 100% of the optical system - that is, completely by the optical chip for optical connection device, it is likely that it will need to be several decades later, it is also necessary to convert the electrical signal into optical signal in some way, and then return.
Fortunately, each optical component can be used to manufacture semiconductor electronics. In fact, it is possible to make electronic and optical components on the same substrate, in order to create a hybrid chip, complete with numerous Telecom and network functions.
In the short term, silicon photonic chips will be deployed in high-speed signal transmission system, it will be far more than the copper cable. Earlier this year, Kotura announced its Engine Optical, which can be achieved by using wavelength division multiplexing 100Gbps data transmission rate, allowing multiple data signals from different wavelengths to share the same optical path. Such equipment is suitable for data center and high performance computing applications, to solve the problem of network performance based on copper wire. IBM, Intel and NEC and other major chip manufacturers are also developing silicon photonic devices.
With the development of silicon photonics, the chip will become more complex, can be expected that the technology will be applied in the multi task processing chip internal link multiple core, improving access to shared cache and bus rate. The final silicon photonics may be more practical and widely used, and even can replace the semiconductor transistor and other optical chips, to obtain higher performance.
