| Researchers Create First Room-Temperature Terahertz Laser Source |
 | The new breakthrough in laser technology comes from Harvard University researchers who have designed and demonstrated the first Terahertz coherent source using room-temperature electrically-pumped semiconductors. The terahertz laser sources commercially available today are based on nanotechnology fabrication techniques, while the new laser technology uses a semiconductor structure to emit radiation. The device is expected to become the new ... [read more >>] |

| Light Creeping Through Small Holes. How It Works |
 | One might imagine that light can basically pass through any hole no matter how small, but the truth is that when presented with a hole smaller than its own wavelength, light finds it especially difficult to penetrate to the other side, but it will nonetheless. Researchers Dr. Aurele Adam and Professor Paul Plancken from the Delft University of Technology used for the first time a technique involving far-infrared light, known as Terahertz r ...
