Progress of quantum-dot photoelectronic devices

Quantum-dot photoelectronic devices are quantum-dot lasers, quantum-dot infrared photodetectors, quantum-dot single-photon sources and quantum-dot optical memory designed and fabricated using quantum-dot microstructures as active regions of the devices, and they have potential applications in optical communication, optical informational process and optoelectronic computer. In this paper, recent progress on the fibricated methods and operating properties of these photoelectronic devices are reviewed, and new developed directions of the field are also predicated.
