“…Its impact can be mitigated by reducing the energy of the fundamental vibration through substitution of the hydrogen atoms by lower-mass atoms, such as deuterium, fluorine, or chlorine. Fluorination of the ligands and polymer host has been shown to reduce the luminescence quenching by high-energy vibrations from C-H and O-H bonds [9,234]. This substitution process has little impact on the loss level of the waveguides produced, allowing e. g. the development of fluorinated polymer waveguides with losses below the level of 0.2 dB/cm at the telecommunication wavelength window around 1.5 μm.…”

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],

“…[9] This work is part of our research that is concerned with the development of a polymer-based optical amplifier in which lanthanide complexes bearing antenna-chromophores are incorporated in planar polymeric waveguides. [3,10] By varying the lanthanide ion in the complex, various emission wavelengths become accessible, and hence optical signals of a range of wavelengths can be amplified. The polymer-based amplifiers can be integrated in existing polymeric optical components such as splitters, switches, and multiplexers.…”

Near-Infrared and Visible Luminescence from Terphenyl-Based Lanthanide(III) Complexes Bearing Amido and Sulfonamido Pendant Arms

et al. 2000

A series of m‐terphenyl‐based ligands bearing three coordinating oxyacetate and two amido or two sulfonamido groups, (1a‐b)H3 and (2)H3, respectively, have been synthesized and characterized. The structures of the corresponding neutral complexes have been studied using 1H‐NMR spectroscopy and luminescence experiments. The photophysical properties of the (1a‐b)Eu, (2)Eu, (1a)Tb, and (2)Tb complexes have been studied to determine the structure of the first coordination sphere in methanol. The first coordination sphere consists of eight donor atoms provided by the ligand (three chelating oxyacetate groups and two amide or sulfonamide oxygens), and one methanol molecule. The (1a)Dy and (1a)Sm complexes exhibited sensitized luminescence in the visible spectral region, but the luminescence intensity was very sensitive to quenching by C‐H groups. The near‐infrared emitting (1a)Ln and (2)Ln complexes exhibited sensitized luminescence at wavelengths (at 880, 1060, and 1330 nm for Nd3+, at 980 nm for Yb3+, and at 1550 nm for Er3+) of interest for applications in optical telecommunication devices. The luminescence lifetimes of these complexes in DMSO and [D6]DMSO are in the range of microseconds. The luminescent state of the NIR emitting lanthanide ions is very efficiently quenched by high frequency oscillators (such as C‐H groups) in the solvent and the ligand.

“…Comparativamente com materiais cristalinos 11 , esta transição também é, aproximadamente, cerca de 10 vezes mais intensa que as transições 4 F 3/2 → 4 I 13/2 (887 nm) e 4 F 3/2 → 4 I 9/2 (1324nm). No caso de outros sistemas poliméricos dopados com íon Nd esta razão decresce para menos que 5 vezes 14,15 .…”

Recebido em 28/6/04; aceito em 18/3/05; publicado na web em 2/8/05 PROCESSING AND OPTICAL CHARACTERIZATION OF POLY(STYRENE SULPHONATE) FILMS DOPED WITH NEODYMIUM. In this work we describe the processing of poly(styrene sulphonate) films (PSS) doped with neodymium (Nd). Optical density measurements in the UV-Vis-NIR region show the typical bands observed for neodymium chloride (NdCl 3 ) in solution. In the case of films, the intensity ratio between the peaks at 800 nm ( 4 I 9/2 → 4 F 5/2 + 2 H 7/2 ) and 580 nm ( 4 I 9/2 → 4 G 5/2 + 2 G 7/2 ) is equal to 0.83. Infrared spectra present an enhancement in the absorption region of aromatic rings. Site selective luminescence spectroscopy shows that the incorporation of Nd introduces a hipsochromic shift and a line shape definition in UV luminescence compared to PSS film, decreasing the interaction between aromatic groups. In addition, the film exhibits an intense radiative transition at 1061 nm ( 4 F 3/2 → 4 I 11/2 ), comparable to the one present in crystalline materials doped with Nd.Keywords: poly(styrene sulphonate); neodymium; films. INTRODUÇÃOO estudo de novos materiais utilizando Terras-Raras (TRs) tem sido explorado nos últimos anos devido ao crescente interesse, principalmente, nas possíveis aplicações tecnológicas em dispositivos fotônicos. Neste caso, os TRs são largamente utilizados, desde a produção de componentes ópticos, vidros e lâmpadas fluorescentes até equipamentos de energia nuclear, estando presentes em eletrodomésticos (refrigeradores), discos rígidos (HDs) de computadores pessoais, catalisadores e muitos outros produtos produzidos por empresas de alta tecnologia 1,2 . Além disso, os lantanídeos (Ln) são de grande interesse científico, uma vez que suas propriedades ópticas não dependem muito do material hospedeiro. Isto se deve a sua estrutura eletrônica, na qual os orbitais mais externos, 5d e 6s, são responsáveis pelas ligações químicas, blindando o orbital 4f que está semipreenchido 3 . Em particular, as propriedades ópticas dos íons de TRs, denominados Ln 3+ , devem-se às fracas interações entre os elétrons do nível 4f e o campo cristalino no qual está inserido. O resultado final é a observação de transições eletrônicas bem definidas, associadas a níveis eletrônicos atômicos.No contexto deste trabalho, o interesse pelo íon Nd 3+ deve-se ao fato deste elemento possuir uma configuração eletrônica envolvendo o nível 4f com transições de alta eficiência quântica e emissão de luz aproximadamente em 1060 nm (atribuída à transição 4 F 3/2 → 4 I 11/2 ) 4 . Devido a isso, o neodímio é considerado um dos elementos de maior interesse na produção de materiais aplicados à fabricação de dispositivos para emissão laser. Outra característica importante deste material é sua distribuição simplificada de níveis (quatro níveis atômicos), o que facilita em muito a inversão de população 4 .Apesar do grande número de trabalhos científicos que empregam estes íons de TRs como dopantes em meio ativo, o uso de matrizes poliméricas como matriz hospedeira não tem sido exp...
