Scientists at the Vienna University of Technology (TU Wien) showed how the branched flow of light can be made to propagate along a single branch rather than along many branches at the same time. Their approach, which they think could be applied to different types of waves, from scalar to vector and from two to three dimensions, is based on shaping the incoming wavefront. The wave signal is then sent exclusively along a single preselected branch and is hardly noticeable anywhere else. The branched flow of lightwaves occurs when an incoming wave splits into several paths, reaching some...Read full articleRelated content from Photonics MediaARTICLESIntegrated Platform for Visible-Light Chip Could Further MiniaturizationTo support the miniaturization of optical devices and components, a scientific team led by researchers at ITMO University has devised a quick, affordable method to make visible-light nanophotonic...Photonics Spectra September 2020 IssueQuantum Entanglement Demonstrated Aboard Orbiting CubeSatAn international research team led by the National University of Singapore (NUS) has generated and detected quantum entanglement onboard a CubeSat nanosatellite weighing less than 2.6 kg and orbiting...Photonics Spectra September 2020 IssueHollow-core Fibers Improve Stability of Light-Based GyroscopesResearchers at the University of Southampton’s Optoelectronics Research Centre, collaborating with researchers from Honeywell, have applied nodeless antiresonant fibers (NANFs) — a...Photonics Spectra March 2021 IssueRUB Scientists Show Radiative Auger Process in Quantum DotsScientists at Ruhr-University Bochum, working with researchers based in Basel and Copenhagen, have demonstrated the connection between the radiative Auger process and quantum optics.

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 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 HandbookMicroscopy Illumination: Considering Nonlaser Light Sources: Metal halide and LED light sources are changing the illumination landscape in microscopy.
