Two-photon counting distributions of different optical sources are experimentally studied using third-order optical nonlinearity in a GaAs detector. Semiclassical as well as quantum theories are presented in order to explain our results.
Optical parametric oscillators (OPO) have been extensively used in the continuous variable quantum optics community as a resource to produce non-classical states of light, including squeezed states or entangled beams. In this paper, general description of multimode OPOs is presented, show that they are able to produce a very wide variety of multimode quantum states of light, and give techniques to...
Frequency doubling of a laser beam in a non-linear crystal has proven to be a very efficient way of accessing new wavelengths. Since it is a nonlinear effect, its efficiency can be improved by inserting the nonlinear medium in a resonant cavity. In this situation the ratio between the output frequency-doubled beam power and the pump power has been measured at values exceeding 80%. However, a single-mode...
Photon bunching in highly chaotic sources (true blackbody and amplified spontaneous emission) is detected for the first time with femtosecond temporal resolution by use of a Hanbury-Brown-Twiss experiment relying on two-photon absorption in semiconductors.
We present here multimode OPOs as a source of multimode squeezing and multipartite entanglement of continuous-wave light beams, with applications to the engineering of multimode states of light in the spatial and spectral domains.
