We report a hybrid organic-inorganic optical upconverter with an embedded mirror, which converts 1.5 μm infrared light to visible light. The device was fabricated through direct tandem integration of an organic light-emitting diode with an inorganic InGaAs/InP photodetector. It was found that the device with an embedded mirror exhibited a low turn-on voltage (∼3.2 V) and an enhanced efficiency. The ratio of photocurrent-induced light with an input power density of 0.67 mW/mm2 versus dark-current-induced visible light was over 500 at a device bias of 6 V at room temperature. The results show that the embedded mirror at the inorganic-organic interface plays a vital role in the performance enhancement of a hybrid upconverter. [ABSTRACT FROM AUTHOR] |
