# Population dynamics and photon emission statistics of the coupled semiconductor quantum dots driven by pulse field

**ABSTRACT** We investigate the population dynamics and the photon emission statistics of the coupled semiconductor quantum dots (QDs) with pulse excitation by using quantum regression theorem and optical Bloch equations. The population of the biexciton state |b〉 is close to those of two exciton states (|x〉 and |y〉) when the effective input pulse area is about π. The calculation results reveal that both the probabilities of the cross single photon emission and the correlated photon-pair emission decrease as the input pulse area increases in every period.

**ABSTRACT:**The book consists of nine chapters. In the first one, Planck’s law is formulated, Einstein’s coefficients are defined, and the principle of action of a laser is described. The second chapter is devoted to the quantum-mechanical description of atom radiation interaction. The Einstein coefficients are calculated, the optical Bloch equations are obtained, and the connection between them and the rate equations are investigated. In the third one, the author describes the statistical analysis of chaotic light sources, different types of interferometers, and the interference patterns that they give in chaotic light. The field quantization is the subject of the fourth chapter. The quantization of electromagnetic field, the interaction of the quantized field with atoms, and the second quantization of the atomic Hamiltonian are analyzed there. The fifth chapter is devoted to single-mode quantum optics, while the sixth one describes multimode and continuous-mode quantum optics. The seventh chapter deals with attenuation and amplification of a light beam, actions frequently needed in experiments. The eighth one is devoted to resonance fluorescence and light scattering. Elastic Rayleigh scattering and inelastic Raman scattering are described in this chapter. An introduction to nonlinear quantum optics is given in the ninth chapter. The book is written as a graduate-level textbook, and over 100 problems help to reinforce the understanding of the material presented.01/2000; Oxford Science Publications. - [Show abstract] [Hide abstract]

**ABSTRACT:**We report the experimental observation of photon antibunching in fluorescence from a single self-assembled InAs quantum dot. The nonclassical photon statistics proves the atomlike nature of a single quantum dot at cryogenic temperatures. Pump-power-dependent measurements of the correlation function g(2)(τ) provide a method to determine the recombination time of the single exciton ground-state transition that does not require pulsed lasers. Using this method, we investigate the influence of photonic environment on a single quantum dot exciton lifetime.Physical review. B, Condensed matter 03/2001; 63(12).

**ABSTRACT:**We describe a mechanism for the production of polarization-entangled microwaves using intraband transitions in a pair of quantum dots. This proposal relies neither on spin-orbit coupling nor on control over electron-electron interactions. The quantum correlation of microwave polarizations is obtained from orbital degrees of freedom in an external magnetic field. We calculate the concurrence of emitted microwave photon pairs and show that a maximally entangled Bell pair is obtained in the limit of weak interdot coupling.Physical Review Letters 10/2005; 95(12):127401.
