Abstract

One of most important conclusions in cavity-quantum-electrodynamics is that spontaneous emission of an atom can be controlled by squeezing zero-point fluctuations of the photon fields surrounding the atom in both spatial and frequency domains.^[1] Considering quantum optoelectronic device application, in addition to quantum control of photon system, it is of great important to control electron system as well in order to alter spontaneous emissions. This can be easily realized in semiconductor systems by a combined use of distributed Bragg reflectors (DBRs) and the quantum confined Stark effect (QCSE) for control of photon and electron systems, respectively. The main purpose of this talk is to demonstrate our experimental results on physical phenomena originating from quantum control of electron- and photon-systems^[2,3], and its implications for device-applications.^[4]
