Ultrafast emission and detection of quantum emitters

We discuss theoretical and experimental results on the ultrafast emission and detection of quantum emitters. We employ nano-antennas, specifically gold nanocones, to accelerate the spontaneous emission rate of silicon-vacancy color centers in diamond by orders of magnitude to generate single photons with picoseconds timescales. Moreover, we implement an optical Kerr shutter under tight focusing to be able to detect such ultrafast single photons with time resolutions down to a few hundreds of femtoseconds.

Intensity squeezed States of lLght from FWM in hot alkali Vapors -Review of Results and Applications

Brana M Jelenkovic, Marija Curcic

Institute of physics, Belgrade Serbia

We review experimental and theoretical results of quantum properties of twin beams generated by the FWM in hot alkali vapors. Noise spectrum of the intensity difference of twin beams and dependence of squeezing on the range of FWM parameters is presented for the FWM in potassium. Relative intensity squeezing of -5.5 dB below SQL requires that potassium density and detuning of the pump and probe laser beams in the double Λ interaction scheme all fall in the rather narrow range.

Generation of nonclassical light in integrated nanophotonic resonators

Marco Liscidini

University of Pavia, Italy

Integrated micro- and nanostructures allow for the efficient generation of photon pairs via parametric fluorescence thanks to the enhancement of the light-matter interaction associated with the spatial and temporal light confinement. These systems grant an unprecedented control over the properties of the generated non-classical light, for the field enhancement can be engineered to enhance or suppress specific nonlinear processes. I will discuss the latest progresses in the generation of photon pairs in integrated devices from two-photon states in linearly uncoupled resonators to bright squeezed light in nanophotonic molecules.
