“…Since the first fabrication of microstructured Polymer Optical Fibers (mPOFs) in Polymethyl methacrylate (PMMA, n=1.49 @589.3nm, 20°C) by Eijkelenborg et al [13], mPOFs have been made using a variety of polymers, such as Topas (cyclic olefin copolymer) [15][16][17] and biodegradable polymers [18]. The standard single-mode mPOF has a triangular hole structure with a single hole size, but much more complicated hole structures can be made, such as the one used to make for example graded-index mPOFs [19,20]. Argyros et al fabricated the first hollow-core bandgap mPOF with PMMA [21] and Cox el al.…”

Abstract:We demonstrate the photonic bandgap effect and the thermal tunability of bandgaps in microstructured polymer optical fibers infiltrated with liquid crystal. Two liquid crystals with opposite sign of the temperature gradient of the ordinary refractive index (E7 and MDA-00-1444) are used to demonstrate that both signs of the thermal tunability of the bandgaps are possible. The useful bandgaps are ultimately bounded to the visible range by the transparency window of the polymer. ©2009 Optical Society of America

“…In particular, the higher loss of the PC fiber compared to its bulk material loss may arise from scattering. There are many possible sources of scattering due to the way mPOFs are manufactured [17,18,41,42]. The drilling process yields surface roughness within the holes of the polymer preform and this fact increases fiber loss.…”

Abstract:Here we present the fabrication of a solid-core microstructured polymer optical fiber (mPOF) made of polycarbonate (PC), and report the first experimental demonstration of a fiber Bragg grating (FBG) written in a PC optical fiber. The PC used in this work has a glass transition temperature of 145°C. We also characterize the mPOF optically and mechanically, and further test the sensitivity of the PC FBG to strain and temperature. We demonstrate that the PC FBG can bear temperatures as high as 125°C without malfunctioning. In contrast, polymethyl methacrylate-based FBG technology is generally limited to temperatures below 90°C. ©2016 Optical Society of America

“…One of the major advantages is that the arrays of air holes are no longer limited to hexagonal structures, and many other geometries are now possible. Improvements in fabrication techniques have also led to lower losses (van Eijkelenborg et al 2004.…”

Optical fibres are not only one of the major components of modern optical communications systems, but are also used in other areas such as sensing, medicine and optical filtering. Silica microstructured optical fibres are a type of optical fibre where microscopic holes within the fibre result in highly tailorable optical properties, which are not possible in traditional fibres. Microstructured fibres manufactured from polymer, instead of silica, are a relatively recent development in optical fibre technology, and support a wide variety of microstructure fibre geometries, when compared to the more commonly used silica. In order to meet the automated design requirements for such complex fibres, a representation was developed which can describe radially symmetric microstructured fibres of different complexities; from simple hexagonal designs with very few holes, to large arrays of hundreds of holes. This chapter presents a genetic algorithm which uses an embryogeny representation, or a growth phase, to convert a design from its genetic encoding (genotype) to the microstructured fibre (phenotype). The work demonstrates the application of variable-complexity, evolutionary design approaches to photonic design. The inclusion of real-world constraints within the embryogeny aids in the manufacture of designs, resulting in the physical construction and experimental characterisation of both single-mode and highbandwidth multi-mode microstructured fibres, where some GA-designed fibres are currently being patented.
