Paper Abstract

Conjugated luminescent polymers have been shown to exhibit stimulated emission under optical pumping. Dilution in polymethylmethacrylate (PMMA) leads to an enlargement, towards longer wavelengths, of the gain region. In addition, ultrafast optical switching is observed when a second pulse is applied during excited state lifetime. These two properties are of high importance for optical communications and can bring to the plastic optical fibres (POFs) the equivalent of erbium amplification in silica fibres. In this communication we report on the gain and switching properties of PMMA films and POFs doped with conjugated oligomers and polymers, prepared by blending or copolymerisation. The dopants were functionalised with polar side groups to improve their solubility in MMA and/or with reactive methacrylate groups so they can be copolymerised with MMA.
