Abstract

One of the most important conclusions in cavity QED is that spontaneous emission of an atom can be controlled by squeezing zeropoint fluctuations of the photon fields surrounding the atom in spatial as well as frequency domains.¹ In addition to quantum control of the photon system, it is important to control the electron system as well, in order to alter spontaneous emissions. This can be easily realized in semiconductor systems by 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 paper is to review our experimental results on physical phenomena originating from quantum control of electron and photon systems,^2,3 and its application in devices.⁴
