Laura S. Marshall,

Technology helps us see, understand and manipulate our world; it helps us communicate from afar; and it helps us shop for shoes without ever setting foot in a mall. And none of it would be possible without the dedicated, forward-thinking researchers and engineers who strive to develop smarter, better, faster, greener gadgets.

Photonics-related technology has been exploding; it seems you can’t check your daily news feed these days without reading about something new in terms of sensors, lasers, machine vision or quantum dots.

Read on for coverage of the latest technological developments.

quantum dots
Also known as QDs. Nanocrystals of semiconductor materials that fluoresce when excited by external light sources, primarily in narrow visible and near-infrared regions; they are commonly used as alternatives to organic dyes.
