Solid-state organic amplifiers and lasers are attractive for hybrid integration due to their compatibility with different material platforms, straightforward processing, and possibility to optimize easily their optical and electronic properties by molecular engineering. Advances in the gain medium design and synthesis in combination with new resonator architectures led to tremendous improvements in temporal and spectral properties, lifetime stability, gains produced and operating threshold powers, which triggered interest in their use for a broad range of integrated photonic applications. In this contribution, the current state-of-the-art in the field of organic solid-state amplifiers and lasers is reviewed from the aspects of fabrication technology, gain materials, and device performance. Furthermore, examples of the progress of this technology from a laboratory curiosity to one that demonstrates practical integrated photonic applications are highlighted. An outlook is also provided on research areas and applications that are likely to shape further developments of this technology. (Figure reprinted from [296],

Segmented-cladding fibers (SCF) consist of a uniform core of high refractive index and a cladding with regions of high and low refractive index alternating angularly, which can effectively realize single mode with a large core diameter. Because polymer optical fibers are usually of large diameter, theoretical model for SCF was further extended to segmented-cladding polymer optical fibers (SCPOF) doped with rare earth complex in this article. On the basis of the physical principle, a material model for SCPOF was established, from which refractive index and glass transition temperature of polymer materials was predetermined for the core and cladding of SCPOF, respectively. According to the model, a preform for SCPOF was fabricated with the core doped with Eu(DBM) 3 Phen that has characteristic emission at 613 nm under excitation at 365 nm. From results of fluorescence photograph, it is clearly seen that the expected preform has been obtained by a two-step method developed in this work.

“…As additives, only lauroylperoxide, as the thermal initiator, and 1-butyl-mercaptan, as the chain transfer reagent, were added to the nitrogen-saturated monomers solution. The combination of lauroylperoxide as the initiator and 1-butyl-mercaptan as the transfer agent is popular for POFs [21,38,39] because lauroylperoxide dissociates to non-gaseous products at mild conditions (t 1/2 = 10 h, 61 • C), thus preventing inclusions or air bubbles in the polymer. The selected ratio from lauroylperoxide to 1-butyl-mercaptan ranging from 0.03 to 0.2 mol % results in the production of polymers with a degree of polymerization, P n , of approximately 900.…”

Waveguides made of poly-methyl-methacrylate (PMMA) play a major role in the homogeneous distribution of display backlights as a matrix for solid-state dye lasers and polymer optical fibers (POFs). PMMA is favored because of its transparency in the visible spectrum, low price, and well-controlled processability. Nevertheless, technical drawbacks, such as its limited temperature stability, call for new materials. In this work, the copolymerization technique is used to modify the properties of the corresponding homopolymers. The analytical investigation of fourteen copolymers made of methyl-methacrylate (MMA) or ethyl-methacrylate (EMA) as the basis monomer is summarized. Their polymerization behaviors are examined by NMR spectroscopy with subsequent copolymerization parameter evaluation according to Fineman-Ross and Kelen-Tüdös. Therefore, some r-parameter sets are shown to be capable of copolymerizations with very high conversions. The first applications as high-temperature resistant (HT) materials for HT-POFs are presented. Copolymers containing isobornyl-methacrylate (IBMA) as the comonomer are well-suited for this demanding application.
