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 ...

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

Modern low-power solutions to computer memory rely heavily on the manipulation of the magnetic properties of materials.

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 ...
