Advances on Applications of Optics and Photonics—Selected Papers from the 7th International Conference on Applications of Optics and Photonics, AOP2026

Dear Colleagues,

The 7th International Conference on Applications of Optics and Photonics, AOP2026, will be held in Portugal’s capital, Lisbon, 7–10 July 2026. Since its first edition back in 2011, the AOP conferences have provided an excellent opportunity to, in an open friendly environment, foster the establishment of the widest range of cooperation projects and relationships with colleagues and institutions involved in optics and photonics research from all around the world. As it is 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.

We are honored to serve as Guest Editors of this Special Issue to be published in Photonics. This Issue will contain a selection of papers submitted and accepted at AOP2026. 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 applications optics and photonics. We warmly invite researchers to submit their contributions, both original research articles and review papers, to this Special Issue. Topics include, but are not limited to, the following:

• Nano-photonics;
• Plasmonics;
• Theoretical optics, quantum and nonlinear optics;
• Optical communications and sensors;
• Optical fibers and applications;
• Biophotonics and biomedical and medical applications of optics and photonics;
• Ultrafast lasers and ultrafast optics;
• Power lasers;
• Optical metrology, image processing and industrial applications;
• Optometry, ophthalmic optics, color and visual sciences;
• Optoelectronics;
• Microwave photonics;
• Photonics and optical instrumentation for space and astronomy;
• Optics and photonics for smart mobility and smart cities.

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.
