Silicon Photonics Manufacturing Ramps Up


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

System Bits: Dec. 31


Low signal loss waveguides With the potential to enable a leap ahead in size reduction and performance, DARPA-funded researchers at UCSB and CalTech have developed new methods to integrate long coils of waveguides with low signal loss onto microchips—potentially enabling a leap ahead in size reduction and performance. Long coils of optical waveguides—any structure that can guide light, ... » read more
