Optical Waveguides in Photonic Crystals

Dear Colleagues,

Photonic crystal structures, including one-, two- and three-dimensional periodic structures, as well as optical fibers with a periodic transverse microstructure, characterized by high refractive index contrast, have an impressing potential for reducing the size, and increasing the functionality, of modern and future photonic devices. They have recently become extremely interesting platforms for the manipulation and nonlinear wavelength conversions of light fields, as well as a base of a number of sensors for the measurement of different physical fields.

The main aim of this Special Issue of Symmetry is discussion of recent achievements in new physical effects including studies of surface state existence in photonic crystal waveguides, methods of photonic stop-band topology improvement, and new nonlinear optical effects realized within optical waveguides in 1D-, 2D- and 3D photonic crystals and photonic crystal fibers. In addition, it is also new findings in design and performance of optical sensors based on silicon, lithium niobate, optically nonlinear layered structures, inorganic materials, and polymers or organic media.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry 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.
