QUEBEC CITY, Canada, April 23, 2019 — For the first time, researchers have successfully 3D-printed chalcogenide glass, a unique material used to make optical components that operate at mid-IR wavelengths. The ability to 3D print this glass could make it possible to manufacture complex glass components and optical fibers for new types of low-cost sensors, telecommunications components, and biomedical devices. Researcher Patrick Larochelle and his colleagues from the Centre d’Optique, Photonique et Laser (COPL) at Université Laval in Canada described how they modified a commercially available 3D printer for...Read full articleRelated content from Photonics MediaARTICLESResearchers Create 3D-Printed Glass with Complex GeometryResearchers from ETH Zürich have developed a technique to produce complex glass objects with 3D printing.

It performs single-ended tests and can calculate fiber attenuation and uniformity and splice and connector losses. It can also locate breaks and determine fiber length. Its ability to locate and measure reflectance and loss makes it the troubleshooting and fault locating equipment of choice. New generation OTDRs include advanced functions such as macrobend location, active-fiber testing and automatic trace acquisition.An optical time-domain reflectometer sends short pulses of light into a fiber and measures its reflections as a function of time. The delay of these reflections to the detector as well as their...Photonics HandbookSpectrum Analysis for DWDM: New Instruments Meet the Challenge: The demand for bandwidth drives a growing need for a new breed of test and measurement instruments.As system and cable installers try to optimize their links, the preferred method has become high-speed DWDM.
