Dear Colleagues,

The Sixth International Conference on Applications of Optics and Photonics, AOP2024, will be held in Aveiro (Portugal), 16–29 July, 2024, organized by the Portuguese Society for Optics and Photonics. Since its first edition back in 2011, the AOP conference has provided an excellent opportunity to, in an open, friendly and stimulating environment, foster the establishment of the widest range of cooperation projects and relationships with colleagues and institutions involved in research and education in optics and photonics from all around the world. Open to contributions in all domains of optics and photonics and application fields, with this conference, we expect to review the state-of-the-art in these subjects and to foresee and discuss the future of research in optics and photonics. A large number of plenary and keynote lectures by world-renowned researchers in all fields of optics and photonics will set the quality standards of a varied and exciting scientific program.

We are honored to serve as Guest Editors of this Special Issue of Applied Sciences, which will showcase a selection of revised expanded and improved versions of papers submitted and accepted at the AOP2024 conference in all subjects relevant to Applied Sciences. Its main scope is to provide a timely and broad collection of the most innovative topics discussed at the latest edition of the conference related to all topics related to applications of optics and photonics. We warmly invite researchers to submit their contributions, both original research articles and review papers, to this Special Issue. Works will be considered on topics in any and all fields of optics. Works of an interdisciplinary nature are particularly welcomed.

Dr. Manuel Filipe P. C. M. Costa
Dr. Sandra Franco

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. 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.
