Advances in Optical Microresonators: Physics and Applications

Dear Colleagues,

Optical microresonators represent a transformative technology, offering precise control over light–matter interactions and driving advancements across the scientific and technological disciplines. The ability to engineer microresonators with tailored geometries and exceptional material properties has catalyzed progress in optical metrology, telecommunications, sensing, and beyond.

This Special Issue aims to collect original research articles and reviews showcasing recent advances in optical microresonators, ranging from their fundamental physics to multifaceted applications. We encourage submissions that exemplify cutting-edge research and highlight the impact of optical microresonators on advancing scientific knowledge and technological innovation. Potential topics include, but are not limited to, the following:

• Microresonator nanofabrication techniques;
• The exploration of new materials for microresonators;
• Frequency comb generation in microresonators;
• Applications of microresonators in lidar, telecommunications, and sensing.

We look forward to receiving your submissions and creating a compelling Special Issue that highlights the latest developments in optical microresonators.

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.
