The Poynting vector in Laguerre±Gaussian beams and the interpretation of their angular momentum density
نویسنده
چکیده
We use the local linear momentum density in Laguerre±Gaussian beams to investigate classically the trajectory of the Poynting vector for light of any polarisation. Some of the diculties of interpretation of the local angular momentum density are discussed. Ó 2000 Published by Elsevier Science B.V.

Exact and geometrical optics energy trajectories in twisted beams
Energy trajectories, that is, integral curves of the Poynting (current) vector, are calculated for scalar Bessel and Laguerre-Gauss beams carrying orbital angular momentum. The trajectories for the exact waves are helices, winding on cylinders for Bessel beams and hyperboloidal surfaces for Laguerre-Gauss beams. In the geometrical-optics approximations, the trajectories for both types of beam a...
متن کاملOrbital angular momentum of Laguerre-Gaussian beams beyond the paraxial approximation.
We derive a full field solution for Laguerre-Gaussian beams consistent with the Helmholtz equation using the angular spectrum method. Field components are presented as an order expansion in the ratio of the wavelength to the beam waist, f=λ/(2πw₀), which is typically small. The result is then generalized to a beam of arbitrary polarization. This result is then used to reproduce the signature an...
متن کاملOrbital Angular Momentum Density of an Elegant Laguerre-gaussian Beam
Based on the method of the vectorial angular spectrum, an analytical expression of the electric field of an elegant LaguerreGaussian beam in free space is derived beyond the paraxial approximation, and the corresponding magnetic field is obtained by taking the curl of the electric field. By using the expressions for the electromagnetic fields, the expression of the orbital angular momentum dens...
متن کاملOrbital and Spin Angular Momentum of Electromagnetic Fields
1 Problem Poynting [1] identified the flux of energy in the electromagnetic fields {E, B} (in a medium with relative permittivity = 1 and relative permeability μ = 1) with the vector S = c 4π E × B, (1) in Gaussian units, where c is the speed of light in vacuum. Abraham [2] recognized the additional role of the Poynting vector as being proportional to the density of linear momentum stored in th...
متن کاملGeneralized ray optics and orbital angular momentum carrying beams
In classical optics theWolf function is the natural analogue of the quantumWigner function and like the latter itmay be negative in some regions.We discuss the implications this negativity has on the generalized ray interpretation of free-space paraxial wave evolution. Important examples include two classes of beams carrying optical orbital angularmomentum—Laguerre–Gaussian (LG) andBessel beams...
