Special Issue Information

Dear Colleagues,

In the last 10 years, there has been an explosion of works on applications of structured light beams in the field of Nanophotonics. In particular, the study of the interaction of nanostructures and arrays of nanoparticles with the angular momentum of light has given rise to studies on the generation of vortex beams, control of the scattering of light, localized excitation of molecules, etc.

For all these reasons, we have decided that a collection of some recent works on this broad topic would be very timely and would raise the profile of this field of research. The topics that this issue will include, but is not limited to generation of angular momentum modes with structured materials, angular momentum dependent scattering of light by nanoparticles, spin orbit interactions of light beams, metamaterials, plasmonics, etc.

This issue concentrates the works of many important contributors to this emergent field of research. This issue will be a cornerstone to defining how structuring light beams can be used to control light matter interactions at the nanoscale.

Best regards,

Prof. Dr. Gabriel Molina-Terriza
Guest Editor

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.

Higher-order orbital angular momentum (OAM) mode guiding in a waveguide which is suitable for on-chip integration has been investigated. Based on the relation between the Laguerre-Gaussian mode and the Hermite-Gaussian mode, it has been shown that two degenerate guided modes of π/2l-rotation symmetry can support the l-th order OAM mode. In order to mimic the rotational symmetry, we have proposed the waveguide structure of a cross-shaped core and designed a waveguide that can support OAM modes of ±1 and ±2 topological charges simultaneously at a wavelength of 1550 nm. Purity of the OAM modes guided in the designed waveguide has been assessed by numerically calculating their topological charges from the field distribution, which were close to the theoretical values. We also investigated the guiding of OAM modes of ±3 and ±4 topological charges in our proposed waveguide structure, which revealed the possibility of the separate guiding of those OAM modes with relatively lower purity.
