Have we finally found the universal substance for photonics? Well, not really. But perovskite, the material (actually, a class of materials) that's recently been getting technical press for its high efficiency as a solar-cell material, has other potential uses as well.

So it is my pleasure to announce (OK, in jest) the launch of a new sister brand, Perovskite Focus World. And if you want to receive the print version, be prepared: in the interests of saving paper, it will be made from . . .
John Wallace was a senior technical editor at Laser Focus World for nearly 25 years, retiring in late June 2022. He obtained a bachelor's degree in mechanical engineering and physics at Rutgers University and a master's in optical engineering at the University of Rochester. Before becoming an editor, John worked as an engineer at RCA, Exxon, Eastman Kodak, and GCA Corporation.
