Secure Quantum Code Sent from Aircraft to Ground Station
LMU Munich physicists succeeded in optically transmitting quantum information between a ground station and a plane in flight, marking the first time that quantum cryptography was used for communication with a mobile transmitter — in this case, a laser-based wireless communications system. The challenge was to ensure that the single photons could be precisely directed at the ground telescope regardless of mechanical vibrations and air turbulence. “With the aid of rapidly movable mirrors, a targeting precision of less than 3 meters over a distance of 20 kilometers was achieved,” said project co-leader Florian Moll. |

Hollow Silica Waveguides for Mid-Infrared Power Transmission and Spectroscopy
Polymicro Technologies
Applications in the Mid-Infrared often require a flexible conduit for transmitting light from source to destination. Hollow Silica Waveguides with an internal Ag/AgI dielectric reflective layer optimized for maximum transmission between 2.5µm and 15µm have been used successfully for applications such as Erbium YAG and CO2 laser power transmission for industrial and medical applications. In addition the waveguides are used as long path flow cells for IR spectroscopy. In the following paper, the physical structure of the waveguides is detailed. Guidelines for handling and optical coupling are discussed. Typical spectral attenuation is shown for example waveguides.
