Next-Generation Optical Networks Communication

Dear Colleagues,

Since the invention of optical fiber in 1966, research and applications of optical fiber communication and networks have never ceased. Currently, optical fiber networks have penetrated every corner of the globe. With the rapid development of technologies such as 6G, artificial intelligence (AI), etc., the demand for optical fiber communication and network bandwidth has increased. New principles and technologies continue to emerge, making exploring next-generation optical fiber communication networks necessary. Anti-resonant hollow-core fibers have continuously pushed the limits of transmission loss reduction and have now entered the deployment phase of hollow-core fiber optic cables, serving as a new medium for future ultra-low latency, ultra-large capacity optical transmission. Multi-core fibers directly interfacing with 800G silicon photonic modules can quadruple single-fiber capacity without requiring FIFO buffers. Breakthrough advancements have also been achieved in 1.6T optical modules with co-packaged optics (CPO), reducing power consumption. In optical switching networks, the emergence of large-port optical switches has significantly reduced the network power consumption of AI data centers, etc. The optical fiber communication research scope is vast, containing fiber and cable technologies, active and passive guided-wave components, integrated optics and optoelectronics, systems and subsystems, networks, and switching. Scenarios combined with AI are also included.

We encourage researchers to publish high-quality papers in Next-Generation Optical Networks Communication. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

• Hollow-core fibers and space division multiplexing fibers;
• Active and passive optoelectronic devices;
• Ultra-high-speed fiber-optic communication system and subsystems;
• Advanced digital signal processing techniques;
• Novel optical networks architecture;
• Optical fiber communication with AI.

I 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.
