As an electromagnetic radiation phenomenon, it’s perhaps not so surprising that light is affected by a magnetic field. This ...

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 ...

Nearly two centuries after Michael Faraday first showed that magnetism can twist light, physicists have uncovered a hidden magnetic ingredient inside this classic effect. The new work reveals that the ...

Light has always been described as an elegant partnership of electric and magnetic fields, yet for nearly two centuries physicists treated the magnetic side as a quiet background player. New ...

Researchers at the Hebrew University of Jerusalem discovered that the magnetic component of light plays a direct role in the Faraday effect, overturning a 180-year-old assumption that only its ...

Block diagram of Faraday effect measurement system using dual-comb spectroscopy. The signal comb (red line) passes through the sample and is superposed with the local comb (blue line). The vertical ...

It’s always interesting to see how scientists and engineers have exploited—in the positive sense of the word—somewhat obscure, fundamental physics principles to create innovative sensors. For example, ...

Osaka, Japan – At the heart of global internet connectivity, optical communications form an indispensable foundation. Key to this foundation are optical isolators, created by combining multiple ...
