Optoelectronic Oscillators (OEO): Principles and Applications

Dear Colleagues,

Optoelectronic Oscillators (OEOs) are promising solutions for the generation of microwave signals with ultra-low phase noise. By hybrid oscillating and interacting in both optical and electrical paths, OEOs exhibit distinguished performance over pure electronic oscillators. Recently, photonic-integrated OEOs have shown us their unique advantages, including being small (in size, weight, and power consumption) and low-SWaP, over conventional OEOs. Moreover, OEOs attract significant interest not only in the field of signal generation, but also in applications such as sensor networks, navigation and meteorology, synthetic aperture radars, space communications, and frequency delivery over ultra-long distances.

This Special Issue aims to provide a comprehensive collection of research that delves into the fundamental principles and diverse applications of OEOs. Aligned with the scope of the journal Photonics, which focuses on the science and technology of optics and photonics, this issue seeks to highlight cutting-edge advancements in the design, optimization, and implementation of OEOs. Our goal is to gather at least 10 high-quality articles which can be compiled into a book. This Special Issue aims to foster innovation and collaboration, serving as a valuable resource for researchers and practitioners in microwave photonics and related disciplines.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but need not be limited to) the following:

• Fundamental principles and mechanisms of OEOs.
• Novel designs and configurations of OEOs.
• Performance optimization, including phase noise reduction, tunability enhancement, or side mode suppression.
• Applications of OEOs in sensor networks, navigation and meteorology, synthetic aperture radars, space communications, and frequency delivery over ultra-long distances.
• Integration of OEOs.

We look forward to receiving your contributions.

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.
