Special Issue Information
Dear Colleagues,
The development of singular optics in recent years ensures the production of novel vortex optical structures. An optical vortex refers to a beam or pulse that has a singularity in phase or amplitude; the latter is also called a polarization vortex. Their stability results from the balance between diffraction and nonlinearity, as well as nonlinearity and angular distribution. These vortex structures are usually created outside the laser cavity by using optical holograms or various optical masks. This opens up new possibilities for the practical application of optical elements creating optical vortices.
Optical vortices have a number of applications in the fields of high-resolution microscopy, optical tweezers, quantum information transfer, information encryption, optical vortex trapping, and many others.
An exciting phenomenon associated with the evolution of laser pulses in optical fibers and planar waveguides is the formation of cnoidal and solitary waves; the latter are called solitons. The soliton regime of propagation is an effect that has been studied in detail by scientists. Regarding the dispersion and nonlinearity of the medium, different types of solitons are observed.
The existence of solitary waves is an interesting subject for optics and laser technologies, and they find applications in modern telecommunications systems and data encryption devices. Research in the field of cnoidal waves and solitons covers scientific areas such as hydrodynamics and optics. Periodic waves are used to describe the behavior of acoustic waves in plasma physics, nuclear physics, biology, and chemistry.

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. Crystals 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 2100 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.
