In this module we will introduce the course on the theory of angular momentum and then introduce the quantum mechanical definition of orbital momentum. We will then use the spherical harmonics to ...

Orbital Angular Momentum (OAM) in optical communications is an exciting area of research that explores how the unique properties of light can be harnessed to enhance data transmission capabilities.

Lixin Guo from Xidian University have shared their perspectives on the past and future of optical metrology involving orbital angular momentum (OAM). The paper explores fundamental principles ...

In this study, a qudit was implemented by the orbital angular momentum state of a single-photon, and dimensional expansion was possible by adjusting the phase of a photon through holographic images.

By using a sophisticated technique involving photon-number-resolving detection and orbital angular momentum (OAM) measurements, the researchers projected a classical pseudothermal light field into ...

"The original Doppler effect could only track movement toward or away from the observer, but the incorporation of orbital angular momentum in both scalar and vector light allows motion tracking in ...
