Abstract
We report a compact light source that incorporates a semiconductor light-emitting diode,nanostructured distributed feedback (DFB) Bragg grating and spin-coated thin conjugatedpolymer film. With this hybrid structure, we transferred electrically generated 390 nmultraviolet light to an organic polymer via optical pumping and out-couple greenluminescence to air through a second-order DFB grating. We demonstrate the feasibility ofelectrically driven, hybrid, compact light-emitting devices and lasers in the visible range.
