Quantum Optics Jena completes ‘seven figure euro’ seed funding 16 Feb 2021 Fraunhofer IOF start-up working to develop photonics-based high-security QKD communication systems and other products. The latest spin-off from the Fraunhofer Institute for Applied Optics and Precision Engineering (IOF) is developing quantum-based solutions for communication systems. This week the founding team announced that it has gathered the necessary investor support for the Jena-based operation. QOJ stated on February 10th, “the security and sovereignty of data is secured by complex mathematical ...

Covid update: 11 February 2021 11 Feb 2021 A round up of this week's coronavirus-related news and countermeasures from the photonics industry. The robot coughs out a precise, repeatable cloud of droplets and aerosols. Research into the spread of coronavirus has been joined by a robot that, unlike a person, can cough out a precisely specified and repeatable consistency of droplets and aerosols. The coughing robot helps determine the effect of masks and various air purifiers on the spread of droplets and aerosols. Measurements made with the robot are also used to verify the accuracy of comput...

Miniature spectrometer offers novel endoscopes and cameras 10 Feb 2021 University of Stuttgart uses 3D printing to create refractive, diffractive and filtering elements. The small stuff: miniature device Advances in direct laser writing and 3D printing have helped the field of micro-optics achieve striking breakthroughs in tiny optical devices, driven by miniaturization philosophies dating back many years. A project at the University of Stuttgart's Institute of Applied Optics (ITO) has now used 3D printing to manufacture a miniature spectrometer, fabricated via two-photon laser writing and ...

It has transformed the field of complex microoptics since the early 2000s. Especially medical engineering ...

New Metamaterial Tiles Improve Sensitivity of Telescopes Written by AZoOpticsJan 27 2021 New metamaterial tiles designed by a multi-institutional research team will help enhance the sensitivity of telescopes that are being constructed at the distinguished Simons Observatory in Chile. Researchers developed new metamaterial tiles that will improve the sensitivity of telescopes at the Simons Observatory by absorbing stray light. The top left photo shows one tile, with its anti-reflective surface shown in the insert. The bottom left photos show the back of the tile, and the right photo shows the ...
