CMOS-based technology will allow low-cost integration of high-speed optical interfaces in silicon Addressing the problem of high-speed interchip interfaces, a technology developed by fabless ...
As AI model parameters surge beyond trillions, the computational clusters required for training grow exponentially. Traditional XPU interconnects now face a critical bandwidth bottleneck that ...
The research team proposed a method called aberration-converged annular lithography (ACAL) system, as schematic diagram shown in Figure 1. The Gaussian beam is converted into a collimated annular beam ...
Copper cabling has been the workhorse for moving data inside of AI and HPC data centers, but fiber is nipping at its heels. Optics brings three possible bandwidth multipliers — wavelength-division ...
