Special Issue Information
Dear Colleagues,
Over the past two decades, rapid advancements in laser technology and cold atom physics have driven remarkable developments in optical frequency standards. The frequency stability and uncertainty of optical atomic clocks now surpass those of the cesium atomic fountain clock by two orders of magnitude; this has triggered a debate and prompted us to launch this Special Issue. Besides metrological applications, optical atomic clocks have already proven to be effective in geodetic evaluations and hold great potential for a wide range of applications in the field of quantum precision measurements and exploration of physics beyond the standard model. These include probing the temporal stability of a fine structure constant, verifying relativistic effects, and searching dark matter and gravitational wave signatures.
This Special Issue aims to highlight the latest advancements in the field of optical clocks, covering new developments in theoretical research, experimental techniques, and emerging applications. We welcome the submission of original research articles, comprehensive reviews, and case studies from researchers, academics, and industry experts.

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.
