Tobias Grossmann,Simone Schleede,Mario Hauser,Mads Brøkner Christiansen,Christoph Vannahme,Carsten Eschenbaum,Sönke Klinkhammer,Torsten Beck,Jochen Fuchs,G. Ulrich Nienhaus,Uli Lemmer,Anders Kristensen,Timo Mappes,Heinz Kalt +13 more
TL;DR: In this paper, the effect of dye concentration on lasing threshold and lasing wavelength was investigated and can be explained using a standard dye laser model, and it was shown that lasing occurs in whispering gallery modes which corresponds well to the measured multimode laser-emission.
Journal ArticleDOI
Integration of active and passive polymer optics.
TL;DR: A wafer scale fabrication process for integration of active and passive polymer optics: Polymer DFB lasers and waveguides and the influence on the laser wavelength from temperature and refractive index changes in the surroundings is investigated, pointing towards the use of the described fabrication method for on-chip polymer sensor systems.
Journal ArticleDOI
Optofluidic tuning of photonic crystal band edge lasers
TL;DR: In this article, the authors demonstrate optofluidic tuning of polymer photonic crystal band edge lasers with an imposed rectangular symmetry and show that the emission wavelength depends on both lattice constant and cladding refractive index.
Journal ArticleDOI
All-polymer organic semiconductor laser chips: Parallel fabrication and encapsulation
Christoph Vannahme,Sönke Klinkhammer,Mads Brøkner Christiansen,Alexander Kolew,Anders Kristensen,Uli Lemmer,Timo Mappes +6 more
TL;DR: All-polymer chips comprising encapsulated distributed feedback organic semiconductor lasers are introduced, and the operational lifetime of the lasers expressed in number of pulses is improved 11-fold and 3-fold in comparison to unencapsulated PMMA devices.
Journal ArticleDOI
Polymer photonic crystal dye lasers as Optofluidic Cell Sensors.
Mads Brøkner Christiansen,Joanna M. Lopacinska,Mogens Jakobsen,Niels Asger Mortensen,Martin Dufva,Anders Kristensen +5 more
TL;DR: Hybrid polymer photonic crystal band-edge lasers are chemically activated to covalently bind bio-molecules or for HeLa cell attachment using an anthraquinone (AQ) UV activated photolinker.
