All-Plastic Organic Lasers with Top-Layer Polymeric Resonators: Tunable Emission through Bending and Application to Refractive Index Sensing.

ABSTRACT: All-plastic thin-film organic lasers, in which all the layers comprising the device (active medium, resonator and substrate) are of polymeric nature, are very interesting because they offer the possibility to tune the emission laser wavelength through mechanical deformation (bending). Here, we report all-plastic distributed feedback (DFB) lasers based on top-layer dichromated gelatin resonators (one-dimensional gratings), active layers of polystyrene doped with perylene orange and substrates of cellulose acetate (CA), showing a successful laser performance, comparable to devices based on fused silica substrates. Remarkably, the emission wavelength of the prepared lasers can be tuned by approximately 10 nm through mechanical deformation (bending) thanks to the polymeric nature of all the la
