One photon and two photon spectroscopy in polymer optical fibres doped with conjugated polymer

The proceeding at: 22nd International Conference on Plastic Optical Fibers (POF 2013), took place in 2013 September,11-13, in Armação dos Buzios, Rio de Janeiro, (Brasil). The event Web site at: http://www.pof2013.org.br/ .In this work, we have compared the characteristics of the spectral emission of plastic optical fibers (POFs) doped with the conjugated polymer poly(9,9 dioctylfluorene)-alt-benzothiadiazole (F8BT), under oneand two-photon excitation. Measurements include evolutions of the fluorescence spectra with excitation wavelength and propagation distance, together with an analysis of the emission photostability.This work has been sponsored by the institutions Ministerio de Economía y Competitividad under projects TEC2009-147-C03-01, TEC2012-37983-C03-01, Gobierno Vasco/Eusko Jaurlaritza under projects AIRHEM-II, S-PE12CA001, IT664-13, and by the University of the Basque Country (UPV/EHU) through program UFI11/16.Publicad
