Optical fibre communication systems have revolutionised global telecommunications by harnessing light‐based signal transmission through highly engineered glass or plastic fibres. The principle of ...

Optical isolation and nonreciprocal devices are pivotal components in modern photonic systems, ensuring unidirectional light propagation and safeguarding sensitive equipment from unwanted reflections.

Spun off from a laboratory at Inha University in South Korea, PhotoniSol, a dynamic startup, is leading the charge in silicon photonic integrated devices. The company focuses on commercializing a ...

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 ...

Physicists have shown that ultra-thin two-dimensional materials such as tungsten diselenide can rotate the polarization of visible light by several degrees at certain wavelengths under small magnetic ...
