Lighthearted Transistor: Electronic workhorse moonlights as laser

10:21am, November 17, 2004

Transistors have long served as the building blocks of microelectronics. More recently, microchip lasers have been emerging as cornerstones of light-based circuitry, or photonics. Now, engineers have melded the two types of components into one miniature device that both amplifies electric current and emits a narrow beam of single-wavelength light.
