Bragg Gratings for Optical Signal Processing

Dear Colleagues, 

From the first demonstration of the formation of a permanent Bragg grating in an optical fiber in 1978 to the most recent proposals of fully reconfigurable waveguide Bragg gratings on a silicon-on-insulator platform, Bragg gratings (BGs) have continued to contribute to the development of new, energy-efficient, high-capacity, fully transparent all-optical networks for telecom and datacom applications. BGs are currently a key component for optical signal processing and are being widely used to increasing the transmission channel capacity, for secure quantum information processing, and for enhancing the performance of microwave photonics. They act as fundamental photonic signal processing units such as optical differentiators, optical integrators, Fourier transformers, Hilbert transformers, ultrafast pulse-shapers, true-time delay elements, and phase-shifters, among others.  

In this Special Issue, we invite submissions exploring the latest developments, applications, and new trends on Bragg gratings technology. Contributions can focus on, but not be limited to, grating design methodology, device fabrication and technology, grating synthesis tools, devices for ultrafast optical signal processing, devices for microwave photonics, Bragg gratings for photonics integrated circuits, reconfigurable Bragg gratings, programable Bragg gratings, and Bragg gratings applications, in general. Survey papers and reviews are also welcomed.

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly 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.
