Special Issue Information
Dear Colleagues,
Optical amplifiers are one of the most important devices for power compensation in long-haul transmission systems and, according to basic amplification principles, they can be divided into three categories: rare-earth doped optical amplifiers, semiconductor optical amplifiers, and nonlinear optical amplifiers. Due to growing demand for the expansion of transmission capacity, optical amplifiers have been developing toward new wavebands and few-mode working states.
The gain, noise figure (NF), and effective waveband are important parameters that determine the signal quality after amplification, and these parameters must be taken into consideration before the manufacturing process. At present, the theory underpinning amplifiers is relatively mature; hence, the parameters of optical amplifiers can be optimized successfully by utilizing theory and modeling.
This Special Issue aims to present original state-of-the-art research articles dealing with optical amplifiers in a broad sense, with special emphasis on their application in long-haul and high-capacity transmission systems. Specifically, papers dealing with different optical amplifiers and their applications, such as few-mode fiber amplifiers, multi-core fiber amplifiers, amplifiers that work in new bands, and optical waveguide amplifiers, are welcome. Researchers are invited to submit their contributions to this Special Issue on topics including, but not limited to:
- Optical amplifiers that work in new wavebands;
- Few-mode optical amplifiers;
- Multi-core optical amplifiers;
- Semiconductor optical amplifiers;
- Fiberoptic parametric amplifiers;
- Rare-earth (co-)doped fiber amplifiers;
- Optical waveguide amplifiers;
- Hybrid optical amplifiers;
- The application of optical amplifiers in different fields.

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.
