Ayar labs is a start-up enterprise aiming to develop high-speed, high-density, low-power “small chips” based on optical interconnection by using novel silicon processing technology. Although the manufacturing process of transistors is still shrinking, copper interconnection between transistors is still a major obstacle to the development of the electronic industry. The key technology direction of Ayar labs is to replace the traditional I / O form. < p > < p > it is reported that the resistance capacitance delay (RC delay) based on copper interconnection is hindering the size shrinkage and speed increase of transistors. Even with insulators based on shielding materials, copper is not reliable at the micro scale. < / P > < p > the company claims that its solution stems from ten years of MIT research cooperation, which combines the technology research experience of UC Berkeley, the University of Colorado and the University of boulder in semiconductor power / performance improvement, and is inspired by research from start-ups such as lightelligence, lighton and lightmatter. < p > < p > compared with the traditional electric signal transmission scheme, the small chip and multi wavelength laser of Ayar labs not only produce less heat, lower signal transmission delay, but also are not easily affected by temperature, magnetic field and noise changes. < / P > < p > in addition, these small chips can increase the interconnection bandwidth density by 1000 times, while the power consumption is only 1 / 10, which is very suitable for the adoption of new system architectures such as AI, cloud, high-performance computing, 5g, lidar, etc. < / P > < p > for example, thanks to the multi port design (eight optical channels), the teraphy chip of Ayar labs can theoretically achieve a bandwidth of tens of TB / s. At the same time, these teraphys have high bandwidth electrical interfaces for switching to silicon chips. < p > < p > Ayar labs has also designed a light source called supernova, which can generate 8 / 16 channels of optical signals, support multiplexing, power distribution, and amplification to 8 / 16 port output. < / P > < p > for system integrators, this intelligent optical I / O chip enables them to focus on the integration of core functions and the development of process technology. At the same time, the I / O tasks are assigned to optical chips with low power consumption and high throughput. Finally, a new system form integrating logic and physical connection is realized.
