Abstract:
Electrically pumped surface emitting organic laser device having a multi-layer of organic materials disposed between a highly reflective microcavity mirror and a highly reflective mirror to thereby form a coupled microcavity. More specifically, the organic laser device includes a substrate; a bottom mirror over the substrate; a layer of spacer over the bottom mirror; a coupling mirror over the spacer layer; an anode over the coupling mirror; an active layer over the anode; a cathode over the active layer; and a top mirror over the cathode. The combination of the electrode and the mirror leads to low optical absorption and highly reflective electrical contacts at organic-electrode interfaces. Electroluminescent emission efficiency is improved due to the realization of efficient electron-injection and hole-injection. A low loss organic laser device with a coupled microcavity structure is realized that can produce surface emitting laser output under electrical pumping.
