Machine Learning Technique Can Rebuild Images That Go Through Multimode Fibers
Using a deep neural network (DNN), researchers reconstructed images transmitted over multimode optical fibers at distances of up to 1 km. In the same way the human brain learns to recognize and categorize images and symbols, the DNN was trained to recognize certain images (in this case, handwritten digits) until it was able to recognize other images that were from the same category.

Blue Light Excites Retinal, Intercepts Cellular Signaling in the Eye
An optical chemistry research study has shown how blue light from digital devices and the sun can cause the death of retinal molecules, increasing potential for age-related macular degeneration. Using live-cell imaging and optogenetic signaling control, researchers showed that blue-light-excited ATR and 11CR can irreversibly change PIP2.

Dark Mirror Coatings
Deposition Sciences Inc. (DSI)
Dark mirror coatings absorb incident light, rather than reflecting or transmitting it. Thus, they simultaneously exhibit both the low transmittance of a metal blocking filter and the low reflectance of an antireflection coating. Dark mirrors are typically used to define the aperture of an optical system where control of stray light...

Glass Doped with Erbium Could Be Used for Optical Circuits
A material created by doping glass made from zinc, sodium, and tellurium with the rare-earth element erbium could be used for broadband planar waveguide amplifiers. Scientists have started testing planar waveguides for use in signal transmission in place of long optical fibers, as waveguides make miniaturization easier.
