As an application of organic semiconductor distributed feedback (DFB) lasers we demonstrate their use as excitation sources in Raman spectroscopy. We employed an efficient small molecule blend, a high quality resonator and a novel encapsulation metho

We present optofluidic lab-on-a-chip devices (LOCs) for single use as disposables. In our approach we are aiming for systems out of poly(methyl methacrylate) (PMMA) that integrate (a) organic lasers, (b) optical waveguides, (c) microfluidic channels,

We demonstrate the feasibility of organic semiconductor lasers as light sources for lab-on-a-chip systems. These lasers are based on a 1D- or 2D-photonic crystal resonator structure providing optical feedback in the active laser material that is depo
