After decades of physics-based theorizing, researchers have succeeded in creating a novel optical metamaterial using conventional materials. Its enhanced electromagnetic effect may make true one-way ...

A research group has discovered significant nonreciprocal optical absorption of LiNiPO4, referred to as the optical diode effect, in which divalent nickel (Ni2+) ions are responsible for magnetism, by ...

A group of physicists from Russia, Sweden, and the U.S. has demonstrated a highly unusual optical effect: They managed to "virtually" absorb light using a material that has no light-absorbing capacity ...

A team of researchers has identified a unique phenomenon, a "skin effect," in the nonlinear optical responses of antiferromagnetic materials. The research, published in Physical Review Letters, ...

Why fast-response, non-contact temperature sensing is needed in biomedical research. How thin, transparent film is used to create the Seebeck effect to measure temperature. The instrumentation ...

An optical effect known as a Brocken spectre is caused when a rainbow halo forms around your shadow, according to the National Park Service. Haleakalā National Park photo An eerie trick of light ...

Researchers at the National Eye Institute (NEI) have discovered that power-producing organelles in the eye’s photoreceptor cells, called mitochondria, function as microlenses that help channel light ...

Plus yet more notable product and system news from this week’s optical communications expo in San Diego. Effect says it “now owns the entire optical coherent technology stack.” Viasat is a ...
