Challenges and Opportunities in Optical Communication Networks

Dear Colleagues,

This Special Issue on “Challenges and Opportunities in Optical Communication Networks” will welcome original research and review articles exploring the latest developments, innovations, and challenges in optical communication systems. As demand for high-speed, high-capacity, and energy-efficient optical networks grows, researchers must address key issues related to network scalability, spectral efficiency, signal processing, and system security.

With the advancement of fiber-optic communication technologies, topics such as coherent optical transmission, photonic integration, nonlinear impairment mitigation, and artificial intelligence applications in optical networks have become critical areas of research. This Special Issue aims to highlight both the challenges and opportunities in modern optical communication networks and to provide insights into novel methodologies and future directions.

We invite contributions in, but not limited to, the following areas:

• Next-Generation Optical Network Architectures;
• Advanced Modulation and Multiplexing Techniques;
• Photonic Integration and Optical Switching;
• Machine Learning Applications in Optical Networks;
• Security and Privacy in Optical Communication Systems;
• High-Speed Optical Transmission and Network Scalability;
• Nonlinear Compensation and Optical Signal Processing.

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 250 words) can be sent to the Editorial Office for assessment.

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.
