Optical necklaces generated by the diffraction on a stack of dielectric wedges
نویسنده
چکیده
We demonstrate that the regular ring-shaped arrays of Gaussian beams, or optical necklaces, can be generated using diffraction on a stack of dielectric wedges. A condition for self-similarity and structural stability of the beams has been derived and shows good comparison with experimental data. © 2008 Elsevier B.V. All rights reserved.

A New Aspect on Wedge Diffraction: Hidden Rays on the Shadow Boundary
The phenomenon of diffraction may be defined by any deviation of geometrical rays from rectilinear paths which cannot be interpreted as reflection and refraction. Although the ascending series solutions to some canonical structures as cylinders, spheres, conducting wedges, etc. are available, they are not directly useful in high frequency region. Those ascending series solutions suffer from ver...

متن کاملGeneration of higher-order optical vortices by a dielectric wedge.
Diffraction of a Gaussian beam with a system of successively located optical wedges is considered. It is shown that the system is able to form higher-order optical vortices.
