FEATURES
Pulsed Lasers Create Optimal Cladding for Tools Lasers are versatile tools with negligible changeover times in manufacturing processes, but in some areas their uses are still suboptimal, such as in welding. Crack formation and problems with fusion...
Wafer-Level Optics Enable Small-Form Photonic Sensors For many years, innovations in sensors for mass markets such as automotive, gaming, and consumer electronics have been driven by the microelectromechanical systems (MEMS) industry. MEMS-based sensors...
EDITORIAL
The evolution continues Over time in optics or any other industry, parallel research and development tracks in areas such as lasers, sensors, and lenses will come together to create a stronger end product. The same is true in publishing: EuroPhotonics has become a special section within select issues of our sister publication Photonics Spectra. European print subscribers to both publications will still receive the...

Nano-antennas Developed for Data Transfer at Light Speed Researchers from the University of Würzburg have developed an electrically driven nanoscale antenna that generates directed infrared light. The technology could be used to exchange data between different processor cores with little loss and at the speed of light. The antenna, called a Yagi Uda antenna, was developed by the nano-optics working group of professor Bert Hecht. The name...
Researchers Create 3D-Printed Glass with Complex Geometry Researchers from ETH Zürich have developed a technique to produce complex glass objects with 3D printing. The method is based on stereolithography, one of the first 3D-printing techniques...
Silver Improves Lightweight Monograin Layer Solar Cells Researchers at Tallinn University of Technology (TalTech) have increased the efficiency of next-generation thin-film solar cells by partially substituting copper with silver in absorber material. A...
Scientists Develop Spectrometer to Detect Molecular Signatures Scientists at the Laboratory for Attosecond Physics (LAP) have developed a spectrometer for the analysis of the molecular composition of biological samples, capable of detecting minimal variations in...
VTT Researchers Develop Optical Fiber Made of Cellulose Researchers from VTT have developed a wood-based optical fiber. The fiber, made from cellulose, is suited for sensors that benefit from biodegradability. In the future, optical cellulose fiber may...
Fluorescent Dye Helps Detect Reactive Oxygen Species Scientists at the University of Bath have developed a fluorescent tool for detecting reactive oxygen species based on a chemical found in mushrooms. Reactive oxygen species (ROS), such as free...
Researchers Aim to Build Light-Controlled Tissue Scaffolds for Cell Regeneration Researchers at Aarhus University are exploring a method of regenerating brain and heart cells using light. Their technique uses water-based nanofibers coated with organic photovoltaic nanomaterials...

Lidar: A Technology at Use in Daily Life Lidars provide point cloud distribution — to represent the 3D environment — using the backscattering of a laser beam from the target surface. They have long been used for purposes of mapping and atmospheric sensing. Lidar is no longer a technology to consider for the future; it is becoming part of our daily lives. Lidars are used in luggage handling, parcel delivery, robotics, and more. Interest...

IR Thermometer The CTlaser G7 IR thermometer from Optris GmbH measures temperatures up to 1200° C on glass components. The device works at a 7.9-µm wavelength which is optimized for low-reflection measurement on ultra-thin flat glass. Measurement errors, caused by the transmission of radiation, are therefore virtually eliminated. The measurement error is 1% of the measuring value, or 1.5° C...
