DRESDEN, Germany, July 2, 2019 — A research team at Helmholtz-Zentrum Dresden-Rossendorf (HZDR), in collaboration with researchers at Technische Universität (TU) Dresden and Deutsches Elektronen-Synchrotron (DESY) in Hamburg, has produced nanowires with operating wavelengths that can be tuned over a wide range by altering the structure of the nanowire’s shell. Fine-tuned nanowires could take on several roles in an optoelectronic component, making the component more powerful, cost-effective, and easier to integrate. The researchers grew gallium arsenide nanowires epitaxially on silicon substrates. Then they...Read full articleRelated content from Photonics MediaARTICLESDevices Made of Multiple Materials Can Fit on a Single ChipA team of researchers at the University of Strathclyde has developed a highly accurate way to assemble multiple micron-scale optical devices extremely close together on a single chip.

Enter Class 1 laser products — lasers that are so safe that the user doesn’t require specific laser safety training or protective eyewear. Some precautions still exist, though.When purchasing an industrial laser system, the astute buyer will look for a Class 1 laser product — a system where the laser beam hazard is completely enclosed and there is no potential laser...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookThin-Film Coatings: A Buyers' Guide: The vast majority of optics used in precision scientific, industrial, biomedical, and military applications incorporate thin-film coatings on their surfaces. Therefore, it’s useful for almost anyone involved in the specification and purchase of optical components to have some familiarity with the typical performance characteristics, trade-offs and limitations of various coating types, as well as some knowledge of the capabilities of common thin-film production technologies. This article provides an objective overview of both these topics.What are thin-film coatings? The purpose of any optical thin-film coating is to modify the transmittance and reflectance properties of the substrate material to which they are applied. Most coatings...Photonics HandbookWHITEPAPERSCharacterization of Advanced Semiconductor Materials and Processes with Nanoscale IR SpectroscopyThis application note demonstrates the successful application of Tapping AFM-IR to distinguish the chemical footprints of several nanoscale lithographic patterns consisting of complex molecular...Photonics.com 3/31/2021Polarization Metrology of Anisotropic MaterialsFull Mueller matrix measurements allow for elimination of ambiguity and a fuller understanding of polarization metrology.
