Talk:Optical vortex

Proposed merge with Orbital angular momentum of light

There's no good reason for two separate articles on this topic, not to mention three. It looks like somebody already added a merger banner for Vortex laser beam. All three pages could presumably be combined into one, since a vortex automatically carries orbital angular momentum. There are some useful distinctions to be made between vortex arrays or networks in optical fields versus pure states of orbital angular momentum, but the articles have a nearly identical scope at the moment. Does anyone have any strong feelings about a merger? Tyharvey313 (talk) 17:39, 2 July 2018 (UTC)

I merged Vortex laser beam into this article, as it appears to be on exactly the same topic. I did not merge with Orbital angular momentum of light because that is a distinct (broader) topic, and I'm not sure that that merge is a good idea. I removed those merge tags. Feel free to re-propose a merge if you like.--Srleffler (talk) 22:42, 19 August 2018 (UTC)

This is a problem.

Why would any article ever have a section titled "Layman's explanation"?

Explanation isn't

"In an optical vortex, light is twisted like a corkscrew around its axis of travel.": what does this mean? — Preceding unsigned comment added by 81.187.201.243 (talk) 01:01, 27 March 2016 (UTC)

Questionable claims and reads like self-promotion

I have the article claimed in this article's first paragraph to be somehow the genesis of optical vortex beams, and optical vortices in general, and find this claim to be quite specious. In the first place, the Nye paper is explicitly directed to acoustics in a quite strained analogy to crystalline dislocations, not optical propagation. As for such general, classical wave mechanics of vortices (what the paper addresses that is generic to optical vortex beams their orbital angular momentum), the study of such wave mechanics was around long before the touted paper. Somebody here is coloring well outside the lines in attempting to promote these specific researchers.Wikibearwithme (talk) 05:43, 31 January 2018 (UTC)

Removed. Per WP:PRIMARY, the interpretation of the role of these researchers in the field requires a reference to a reliable secondary source. A reference to their paper is not sufficient.--Srleffler (talk) 06:52, 31 January 2018 (UTC)

Underwater imaging application

If/when these pages get merged: US Navy researchers are developing underwater imaging platforms using optical vortex/OAM filtering to sense objects despite significant backscatter caused by turbidity and to build transmissometers. DesTROYer22Alpha (talk) 14:57, 2 April 2020 (UTC)

Rendered animated beam

Researchers at King's College London have created some physically accurate renders of a focused optical vortex, in the form of a Laguerre-Gaussian 1,0 mode. We would like to insert the following video into this article, and would welcome any suggestions/comments from the community. The 3D animation helps the reader conceptualize the spiralling nature of the wavefronts, how they propagate with time, and highlights how the positive and negative regions of the Laguerre polynomial functions give rise to a double-helix structure.--J.Kingsley-Smith (talk) 17:09, 19 January 2022 (UTC)
