Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

Researchers from the National University of Singapore (NUS) have achieved exciting progress in quantum metrology, a field ...

Coherent's AI datacom demand and next-gen optics drive growth. Our model predicts 12% FY26 revenue rise and a 490bps margin ...

With the continuous growth of network traffic, optical wireless communication (OWC) technology based on orbital angular momentum (OAM) can meet the needs of large-capacity modern communication and is ...

In this work, we experimentally investigated the gain characteristics of a ring-core erbium-doped fiber (RC-EDF) that supports five orbital angular momentum (OAM) mode groups. Through the design and ...

Optical physics is the study of the fundamental properties of light and its interaction with matter. This includes classical optical phenomena such as reflection, refraction, diffraction and ...

Optics and photonics covers the entire electromagnetic spectrum from high-energy gamma rays and X-rays, through the optical regime of ultraviolet, visible, and infrared light, to long-wavelength ...
