Researchers Make Transparent Materials Absorb Light
Researchers have demonstrated an optical paradox — they have made a completely transparent material appear perfectly light-absorbing. The results of their research contradict the idea that materials that look transparent, such as glass, appear that way because they have no light-absorbing qualities.

That Was Then, This Is Now: Fiber Optic Cables Find New Use as Seismic Sensors
The decade that gave us the Sony PlayStation also gave us dark fiber — an excess of optical fiber cables installed underground, mostly in the 1990s, before advances in data transmission reduced the need for all those cables. Now, research teams on the earthquake-prone West Coast of the U.S. are putting dark fiber optic cables to use as sensor arrays for seismic monitoring.

Hybrid Perovskite Material Could Be Key to Making Organic Diode Lasers
Researchers are closer to creating a tunable semiconductor diode laser from hybrid organic-inorganic perovskites. Using a material composed of an inorganic perovskite sublattice with relatively big organic molecules confined in the middle, a Penn State research team demonstrated that optically pumped continuous-wave lasing could be sustained for over an hour.

Single-Shot Approach to HSI Uses Camera Equipped With Prism
A compact, low-cost, single-shot hyperspectral imaging method has been devised, which captures images using a conventional DSLR camera equipped with an ordinary refractive prism placed in front of the lens. The new, user-friendly method was tested on a variety of natural scenes, and the results, according to the researchers, compared well with current state-of-the-art hyperspectral imaging systems.
