Photonic mode dispersion of a two-dimensional distributed feedback polymer laser

We present an analysis of the photonic mode dispersion of a two-dimensional ͑2D͒ distributed feedback polymer laser based on the conjugated polymer poly͓2-methoxy-5-(2Ј-ethylhexyloxy͒-1,4-phenylene vinylene͔. We use a combination of a simple model, together with experimental measurements of the photonic mode dispersion in transmission and emission, to explain the operating characteristics of the laser. The laser was found to oscillate at 636 nm on one edge of a photonic stop band in the photonic dispersion. A 2D coupling of modes traveling perpendicular to the orthogonal gratings was found to lead to a low divergence laser emission normal to the waveguide. At pump energies well above the oscillation threshold for this mode, a divergent, cross-shaped far-field emission was observed, resulting from a distributed feedback occurring over a wide range of wave vectors in one band of the photonic dispersion.

“…Phenylene-based materials are among the conjugated polymers, one of the most important class of compounds for electronic applications especially as blue emitting materials in organic light-emitting diodes (OLEDs), [1,2] plastic lasers, [3] and photovoltaic devices. [4] The poly( pphenylenes) [(1), PPP, Figure 1] suffer from the drawback that the unsubstituted derivate is an insoluble blue emitter, and that the introduction of solubilizing groups leads to a torsion of the backbone which yields a hypsochromic shift of the emission.…”

A novel poly(p‐phenylene) (6) has been synthesized by a cruciform combination of a polyphenylene backbone with 2,2′‐(p‐phenylene)‐bis(4,5‐diphenylimidazole) (5) as an additional, orthogonal chromophore. Polymer 6 showed in solution and in the solid state, a blue‐green emission, which is obviously arising from the second bisimidazole‐based chromophore. UV‐Vis spectroscopy, and cyclic voltammetry revealed that the optical and electronic properties of 6 were fully determined by the incorporated 2,2′‐(1,4‐phenylene)bisimidazole structure. The bisimidazole unit led to high solubility and, despite the steric demand of the substituents, at the same time to the blue‐green emission of the poly(p‐phenylene) (6). In addition, the oxidation of 6 with potassium ferricyanide yielded a low bandgap polymer with a quinoid‐type structure and a bandgap of 1.6 eV.magnified image

Die organische Optoelektronik basiert auf einer Klasse neuartiger Materialien: „Plastik”︁ mit den elektronischen und optischen Eigenschaften von Halbleitern. Großflächige Leuchtdioden aus organischen Materialien halten zurzeit Einzug in verschiedene Bereiche der Bildschirmtechnologie. In den hierbei verwendeten dünnen organischen Schichten konnte nun auch optische Verstärkung und Lasertätigkeit nachgewiesen werden (Abb. 1). In diesem Artikel diskutieren wir die zugrunde liegende Photophysik und geben eine Übersicht über die bereits erzielten Erfolge auf dem Weg zu neuartigen organischen Laserbauelementen.
