Special Issue Information

Dear Colleagues,

Polymer optical fibers (POF) have been proved during the last years as very attractive fibers due to large sensitivity to external environment, biocompatibility and easy handling amongst other advantages. Short distance telecommunications and sensing have been identified as fields with an increasing number of potential applications.

Local area networks and interconnection based on polymer optical fibers have been demonstrated with successful data rates whereas further work on new materials and components is identified as a promising field for increasing the scope of these fibers. Moreover, sensors based on polymer optical fiber technology have been proposed a long time ago, nonetheless, they are currently under dynamic and fruitful fundamental and applied research with upcoming new applications and developments. In this context, polymer optical fiber technology is a growing research and application area at the intersection of health and general engineering.

The purpose of this Special Issue is to collect advances in fundamental research, development of technologies, as well as innovative applications of polymer optical fibers for communications and sensing.  

It is our pleasure to invite you to submit original research papers, short communications or state-of-the-art reviews within the scope of this Special Issue. Contributions can range from fundamental properties of polymer fibers, their fabrication and characterization, as well as innovations in processing technologies for the development of applications.

Topics include, but not limited, theoretical and experimental original work on the following:

  • New polymer fibers: materials and special structures (photonic crystal fibers, S-, U- D-type, etc)
  • Polymer optical fiber networks: indoor, in-vehicles, etc.
  • Multiformat signal transmission over polymer fibers
  • POF transceivers

We proposed a refractive index (RI) sensor employing two twisted tapered plastic optical fibers (POFs). The tapered POFs were fabricated by a heating and drawing method and were twisted around each other to form a coupled structure. The sensor consisted of two input ports, a twisted region, and two output ports. The tapered POF could make the light couple from one POF to the other easily. The twisted tapered POFs could constitute a self-referencing sensor, and by monitoring the changes of the coupling ratio, the variations of the external medium RIs could be measured. The RI sensing performances for the sensors with different fiber diameters and twisted region lengths were studied. The sensitivities of 1700%/RIU and −3496%/RIU in the RI ranges of 1.37–1.41 and 1.41–1.44 were obtained, respectively. The sensor is a low-cost solution for liquid RI measurement, which has the features of simple structure and easy fabrication. Full article

This paper presents a review of the development of optical fibers made of multiple materials, particularly including silica glass, soft glass, polymers, hydrogels, biomaterials, Polydimethylsiloxane (PDMS), and Polyperfluoro-Butenylvinyleth (CYTOP). The properties of the materials are discussed according to their various applications. Typical fabrication techniques for specialty optical fibers based on these materials are introduced, which are mainly focused on extrusion, drilling, and stacking methods depending on the materials’ thermal properties. Microstructures render multiple functions of optical fibers and bring more flexibility in fiber design and device fabrication. In particular, micro-structured optical fibers made from different types of materials are reviewed. The sensing capability of optical fibers enables smart monitoring. Widely used techniques to develop fiber sensors, i.e., fiber Bragg grating and interferometry, are discussed in terms of sensing principles and fabrication methods. Lastly, sensing applications in oil/gas, optofluidics, and particularly healthcare monitoring using specialty optical fibers are demonstrated. In comparison with conventional silica-glass single-mode fiber, state-of-the-art specialty optical fibers provide promising prospects in sensing applications due to flexible choices in materials and microstructures.
