Introduction: the silicon laser technology based on Photonics more widely used in computer, because the use of large-scale silicon manufacturing technology can reduce the cost greatly. The device uses the III-V semiconductor light-emitting characteristics, and the use of sophisticated CMOS technology on silicon wafers on the production of lasers, so as to create low-cost mass production of silicon optical devices opened the door.
OFweek laser network news: Intel is the world's largest manufacturer of semiconductor chips, it was founded in 1968, has 44 years of product innovation and market leadership history. 1971, Intel launched the world's first microprocessor. The computer and Internet revolution brought by the microprocessor changed the whole world.
Intel, which is derived from the predecessor of Fairchild Semiconductor Corporation and development. Fairchild Corp founder William Shackley was the 1956 Nobel prize in physics, because of the invention of the transistor and changed the history of science and technology, won the 1956 Nobel prize in physics.
Latest hybrid silicon laser technology
In April this year, Intel CTO Justin (Justin Rattner) held in Beijing Intel Information Technology Summit via video first public demonstration for the running status of the data center, speed up to 100gbps fully integrated silicon photovoltaic modules. This is the only one in the world to use a hybrid silicon laser module. Justin revealed that this module will achieve production. The industrialization of silicon photonic technology has been a significant breakthrough in the application of the technology.
The use of the world's first standard silicon manufacturing process of hybrid silicon laser power
The so-called silicon photonic technology is the integration of the optical module into the traditional silicon based chip, the use of chip production process and packaging technology, large-scale production of photovoltaic modules, so as to achieve the optical transmission between the chip. It is believed to bring another revolution in information technology. In this new wave of technological revolution, the United States as the representative of the United States Intel once again in the forefront of the world. Due to the silicon material is more suitable for transmission circuit and not light, so through the silicon produced laser especially continuous laser is a very difficult thing, to realize industrialization, more need to solve a series of difficult technical problems.
Silicon is widely used in mass production of digital electronic products. It is also used for routing, detection, modulation and amplification of light. On the other hand, the laser based on Indium Phosphate is widely used in telecommunication equipment, but it needs to be combined and calibrated one by one. This is relative to the computer industry in large quantities, low cost manufacturing needs, is still too expensive and time consuming.
Hybrid silicon laser has a unique design, when the silicon waveguide to accommodate and control the laser, its use of Indium Phosphate material can produce light and expand it. The key to making this kind of equipment is to use low temperature oxygen plasma (with charged oxygen) to form a thin oxide film on the surface of these two materials (about 25 atoms thick).
When heated at the same time pressure on both sides of the material, the two materials on the oxide film as a glass adhesive, and the fusion of the two materials into a single chip. To apply a voltage to the Indium Phosphate, which produces the light through the film, which is the same as a glass binder, into the silicon waveguide. Waveguide to hold and control light, forming a hybrid silicon laser. The design of waveguide is crucial to the performance of the hybrid silicon laser and the wavelength of the laser.
In fact, from the beginning of last century, Intel began to develop silicon photonics technology, is one of the world's first companies to begin research and development of silicon photonics technology, but in a long period of time there is not much progress. 2004, Intel researchers for the first time demonstrated a bandwidth of more than 1GHz silicon laser modulator, than the previous silicon based modulation recorded nearly 50 times faster. In 2005, they announced the development of the world's first set to drive the first set of continuous wave silicon laser technology, until 2006 only developed the world's first hybrid silicon laser.
