Vortex Beams: Transmission, Scattering and Application

Dear Colleagues,

Vortex beams have recently received significant attention because of their spiral phase distribution with orbital angular momentum (OAM). They have been widely used in light scattering, optical tweezers, optical wireless communication, and advanced optics filed regulation. Vortex beams can be expanded into a series of superimposed plane waves, and their interaction with matter will produce different scattering field distribution characteristics related to the topological charge and half-conical angle. Their unique light field distribution characteristics trap particles with a low and high refractive index, realizing optical manipulation as needed. The OAM of vortex beams has also been exploited to improve the data transmission capacity of free-space optical communication, which provides a new dimension outside of the amplitude, phase, wavelength, and polarization of light fields. Therefore, research on the propagation of vortex beams in atmospheric turbulence and OAM mode detection will contribute to OAM optical communication. We believe that advances in these research fields will push this technology forward.

This Special Issue will cover a range of topics from the field including, but not limited to, the following:

• Vortex beam scattering;
• Propagation of optical beams in atmospheric turbulence;
• Vortex beam transmission in multilayered medium;
• Regulation of vortex beam fields;
• Optical manipulation by vortex beams;
• Atmospheric optics;
• Orbital angular momentum state recognition;
• Optics communications;
• Terahertz vortex beams, networks, and systems;
• Vortex beams and OAM modes;
• Applications of vortex beam scattering and propagation.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Photonics is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
