Special Issue Information
Dear Colleagues,
The topic of specialty optical fibers has enabled the development of a vast research area in the field of photonics that ranges from sensing over light shaping and delivery to special light sources. This research has been enabled by the extension of the optical fiber concept from a simple cylindrical waveguide with a core and cladding region of extremely pure undoped and doped silica glass to a tiny, eventually microstructured device that can be made from a large number of materials and material combinations.
Indeed, the success of optical fibers started with communications systems as one of the key technologies of our society. The underlying production technique that allowed this marvelous journey to start was MCVD. The extremely high purity of the glass produced with that technique allowed the production of fibers that could carry light pulses and hence information over hundreds or—after the invention of the erbium fiber amplifier—thousands of kilometers. The successful MCVD method established itself as the de facto standard for fiber production. However, highest purity and lowest losses are not always needed, and relaxing these requirements opens up myriad new applications that are based on new fiber materials and their combinations, as well as on microstructured fibers. To that end, novel production techniques and methods have been developed. Pre-fabricated elements such as capillaries and tubes allow the production of microstructured fibers by the stack-and-draw method; powder-based techniques allow many materials to be mixed and the production of active or passive fibers or fiber elements by the powder-in-tube technique or by sintering and vitrification techniques; the direct deposition of nanoparticles allows active fibers to be built with excellent control of the dopants; coating techniques like sol–gel allow the active fiber cores to be homogeneously doped at high dopant concentrations.
The present Special Issue will comprise a collection of articles reporting recent results on specialty fibers that show the state of the art with respect to functionality, performance, losses, and perspectives in the field of specialty optical fiber production.

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. Applied Sciences 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).
