Silicon Photonics Manufacturing Ramps Up

By Gregory Haley - 21 Mar, 2024 - Comments: 0

Circuit scaling is starting to hit a wall as the laws of physics clash with exponential increases in the volume of data, forcing chipmakers to take a much closer look at silicon photonics as a way of moving data from where it is collected to where it is processed and stored. The laws of physics are immutable. Put simply, there are limits to how fast an electron can travel through copper. The... » read more
