Measurement of light's orbital angular momentum
2013The desire to increase the amount of information that can be encoded onto a single photon has driven research in many areas of optics. One such area is the study of the orbital angular momentum (OAM) carried by a light beam. These beams have helical phase-fronts and carry an orbital angular momentum of l_hbar per photon, where the integer l is ...

Angular momentum of a rotating light beam
Optics Communications, 2005Abstract The structure and mechanical properties of a light beam, which is forcedly rotated around the propagation axis, are considered on the ground of the beam representation by superposition of axially symmetric optical-vortex beams (for example, Laguerre–Gaussian modes) with concertedly shifted frequencies.

Angular momentum of rotating paraxial light beams
Journal of Optics A: Pure and Applied Optics, 2005We investigate the total angular momentum (AM) of paraxial light beams that slowly rotate around the propagation axis. The correction of the first order in angular velocity is obtained to Berry's formula giving the ratio of the total AM in the cross-section to the linear energy density for an arbitrarily polarized paraxial beam (Berry 1998 Proc.

Measuring the orbital angular momentum of light
SPIE Proceedings, 2011We report a new simple optical system for the highly efficient measurement of the Orbital Angular Momentum States of Light. It uses an image reformatter to map each input state onto a different lateral position in the output aperture. This, near perfect, separation of states potentially makes available the high information capacity of OAM in both ...

IV The Orbital Angular Momentum of Light
1999Publisher Summary This chapter discusses the orbital angular momentum of light, outlines the theoretical basis for the orbital angular momentum of beams within the paraxial approximation, and indicates the unapproximated theory, based on the full set of Maxwell equations.
