Advanced Technique and Future Perspective for Next Generation Optical Fiber Communications

Dear Colleagues,

With the emergence of various applications, higher requirements are put forward for optical communication systems and network capacity. Especially since the COVID-19 epidemic this year, the whole world has been seriously affected. New types of businesses such as remote work and online teaching have led to a blowout growth in global network traffic and instantaneous traffic keeps refreshing records. With the development of DSP technology, the coherent optical communication system with complex modulation has greatly improved the capacity of single-mode fiber by improving the spectral efficiency. As the optical communication system and network become more and more complex and huge, novel effective methods need to be proposed to meet the new challenges. Artificial intelligence (AI) technology has made great progress in recent years and has been the focus of broad interest. The increasing complexity of optical communication systems and networks has stimulated the application of AI, covering performance monitoring, equipment and network control, and management. Although the application of AI in optical communication is still in its infancy, it has great potential in the future.

This Special Issue will explore advanced analytical tools and novel technologies for next-generation optical fiber communication systems and networks. It will focus on state-of-the-art advances and future perspectives from fundamental theories to applications and also including devices, subsystems, and networks. Topics of interest include, but are not limited to, the following areas:

• Nonlinear fiber optics
• Advanced devices
• DSP for direct detection and coherent detection technique
• Advanced modulation format and pulse shaping technology
• Ultra-wideband optical fiber communication system
• AI and deep learning application in optical fiber communication
• Optical network control and management

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.
