Abstract:Surface‐emitting organic distributed feedback (DFB) lasers are attractive devices for label‐free sensing applications. Of particular interest for cost‐reduction purposes are devices in which both active material and resonator are based on solution‐processable polymeric materials. Here, the capability for label‐free refractive index sensing of DFB devices consisting of top‐layer resonators (1D relief gratings) of dichromated gelatin layers is reported, deposited on top of active films of polystyrene doped with … Show more
