Photonics Set to Rescue Microprocessor Clocking

Facebook X LinkedIn Email
A brick wall looms for electronic clocking, but photonic techniques offer a path to higher speeds.

James P. Siepmann, LightTime LLC

In the fast-paced and ever-changing microprocessor world, there is one undeniable truth: Photonic clocking will happen. It is just a question of when. The International Technology Roadmap for Semiconductors, which has been accurate in laying out future microprocessor technologies, makes it clear that the electrical clocking technology will meet its demise somewhere between 2008 and 2012, which correlates to clock speeds of about 8 to 10 GHz.1 (The public is particularly familiar with the core clock speed rating of microprocessors, so it is used in this article rather than the local clock...Read full article
