New research has demonstrated how the nano-architecture of a silkworm’s fiber causes “Anderson localization of light,” a discovery that could lead to various innovations and a better understanding of light transport and heat transfer. The discovery also could help create synthetic materials and structures that realize the phenomenon, named after Nobel laureate Philip Anderson, whose
Engineers have taken one of biotech’s hottest tools—optogenetics—and made it better. The 12-year-old technique, which enables scientists to control brain cells with light, typically requires a multi-step process and several surgeries on animal models. Polina Anikeeva at the Massachusetts Institute of Technology (MIT) and her colleagues came up with an engineering solution that combines those
Pulse lasers built entirely on optical fibers are increasingly readily being used by industry. Optical scientists from the Warsaw Laser Centre of the Institute of Physical Chemistry of the Polish Academy of Sciences and the Faculty of Physics of the University of Warsaw have generated ultrashort laser pulses in an optical fiber using a method
