Photonics Focus Magazine Vol. 2 Issue 3

May/June 2021 | Vol. 2 | Issue 3

1958 was a big year for photonics. It set the stage for the foundations of modern industry.

This issue of Photonics Focus explores the tools at the heart of modern commerce, from the wonderous chip, which has doubled the density of transistors in a circuit every few years as it inches toward the conclusion of Moore's law, to advanced laser technology.

Select articles are available online, but the complete issue is available for download as a PDF.

Chip manufacturers have solved hard engineering problems for decades. But making the production process safer for the environment might be the hardest problem they have faced
The prodigal microchip
Lasers interrogate materials to simulate extreme conditions and detect defects at the nanoscale
Photons go to extremes
Using optical hardware, neuromorphic computing can replicate the human brain’s singular visual processor
Brainstorming the next generation of computing
