The optical device has dual functions of optical power amplification and photon energy up-conversion. The optical amplifier device consists of an InGaAs/InP based HPT structure as photodetector, gold-coated metals as embedded mirror and a top-emission OLED. New optical up-conversion imaging devices are also provided that include focal-point array of the organic/inorganic hybrid optical amplifier devices in pixelated formats. The up-conversion imaging devices have a fast response time to enable gated operation for practical applications such as night vision, active surveillance, semiconductor wafer inspection and eye-safe infrared imaging. More importantly, the up-conversion imaging devices would be particularly useful for detecting ultra-low intensity infrared scenes.
