The State-of-the-Art in Optical Fiber Research

Dear Colleagues,

Modern technologies developed based on optical fibre in the last few decades have achieved significant success in different research fields (e.g., communications, physics, biology, chemistry, materials, medicine, earth science, computer science, etc.), with a variety of applications in data communications, material processing, sensing, detection, monitoring, and for light computing purposes. Due to advantages such as low-cost implementation, compact size and low weight, immunity to electromagnetic interferences, chemical resistance, long distance transmission and large multiplexing capability, optical fibres are steadily being utilized in applications ranging from home broadband to aero-spacecraft sensors. Hence, optical fibre research, as a traditional and fundamental discipline, plays an important role in aspects of our daily life to national defence alike.

The aim of this Special Issue is to highlight the latest developments and trends in state-of-the-art optical fibre research (technical, numerical, and methodological) through the collection of articles covering recent improvements in, but not limited to, the following areas of interest:

• Basic and fundamental theory of optical fibre and optical fibre-based systems in long-haul, medium-haul, and short-haul communications;
• The design, fabrication, and application of special fibres (e.g., photonic crystal fibre (PCF), microstructured fibre);
• Optical fibre (bio/chemical/physical) sensing devices (fibre Bragg gratings (FBG) and PCF-based surface plasmonic resonance (SPR));
• Optical fibre devices/systems for high-speed 5G and 6G Internet communication and networks;
• Optical fibre laser, sources, and amplifiers;
• Nonlinear fibre optics.

Contributions from all areas of research involving optical fibre are welcome. We are pleased to invite you to participate by submitting original research papers, communications, and review articles to provide broad insight into recent developments and the future outlook in this Special Issue.

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 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. Electronics is an international peer-reviewed open access semimonthly 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.
