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 ...

The arrows indicate the direction in which the light travels, and the size of the cylinder indicates the intensity of the light. The intensity of light transmitted through a magnetic material (the ...

The research team at Fraunhofer IAF has succeeded in combining two active media, an NV diamond and a laser diode, in an optical resonator and thus demonstrating the laser threshold for the first time.

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 ...
