Tailored Photons Generated from Solid-state Chips
Researchers at the Cavendish Laboratory at Cambridge University have implemented a novel technique to generate single photons with tailored properties from solid-state devices that are identical in quality to lasers. A semiconductor Schottky diode device containing individually addressable quantum dots was built as their photon source. The transitions of quantum dots were used to generate single photons via resonance fluorescence – a technique previously demonstrated by the same team. |

Endoscope Prototype Is Thin as a Human Hair
The micro-endoscope, developed under Stanford University's Joseph Kahn, can resolve objects about 2.5 µm in size (beating today's high-resolution endoscopes by about 8 µm), with a resolution of 0.3 µm within reach. |
