We demonstrate that spatial quantum correlations are induced by multiple scattering of squeezed light. The correlation relates multiple scattered photons at different spatial positions, and is tunable by varying photon fluctuations of the illuminating beam.
We measured time-resolved photoluminescence from large quantum dots near a semiconductor-air interface. Far from the interface our data are consistent with dipole theory, but near the interface they question the validity of the dipole approximation. c2008 Optical Society of America.

InAs quantum dots have been placed at different distances to a silver mirror. We extract the coupling of quantum dots to surface plasmon polaritons as a function of the distance by time-resolved spontaneous emission measurements.
We define a practical measure for the degree of fractional decay and establish conditions for the effect to be observable for quantum dots in photonic crystals exhibiting absorptive losses.
Here we present quantitative measurements of the dipole moment of an ensemble of self-assembled quantum dots employing a modified optical local density of states (LDOS). The LDOS is controlled by varying the distance from the QDs to a semiconductor/air interface.
The authors demonstrates that spatial quantum correlations are induced by multiple scattering of quadrature squeezed light through a random medium. As a consequence, light scattered along two different directions by the random medium will not be independent, but be correlated to an extent that can only be described by a quantum mechanical theory for multiple scattering. The spatial quantum correlation...
We have measured time-resolved spontaneous emission from quantum dots in 3D photonic crystals. Due to the spatially dependent local density of states, the distribution of decay rates varies strongly with the photonic crystal lattice parameter.
It is experimentally demonstrated how quantum noise of light is transported through a multiple scattering random medium. We predict the existence of novel spatial quantum correlations that are induced by multiple scattering.
We present experimental studies on spontaneous emission of CdSe quantum dots (QDs) embedded in 3D photonic crystals consisting of air spheres in titanium dioxide
A weakly nonlinear multiple-scales analysis is performed for singly resonant second-harmonic generation. Coupled amplitude equations are derived that describe pattern formation above the transverse instability threshold. The amplitude equations explain the absence of roll patterns and are in good agreement with numerical results.
We demonstrate generation of ( corrected for the output mirror reflection) of the cw coherent blue light around by frequency doubling of only from a diode laser. With IR power of we reach the doubling efficiency of . The overall conversion efficiency from the electrical power into the blue light is...
