optical hyperparametric oscillations in a whispering gallery mode resonator threshold and phase diffusion
Physical Review A, 2005Co-Authors: Andrey B. Matsko, Vladimir S. Ilchenko, Anatoliy A. Savchenkov, Dmitry Strekalov, Lute MalekiAbstract:We present a theoretical analysis of optical parametric oscillations through four-wave mixing in a nonlinear high-$Q$ whispering-gallery-mode resonator. It is shown that even a small flux of Pump photons is sufficient to reach the threshold of the oscillations. We demonstrate that due to narrow bandwidth of the resonator modes as well as the high efficiency of the resonant frequency conversion the oscillator produces a stable narrow-band beat note of the Pump, Signal, and idler waves making an all-optical secondary frequency reference feasible.

Low threshold optical oscillations in a whispering gallery mode CaF 2 resonator
Physical Review Letters, 2004Co-Authors: Anatoliy A. Savchenkov, Vladimir S. Ilchenko, Andrey B. Matsko, Makan Mohageg, Dmitry Strekalov, Lute MalekiAbstract:We have observed low-threshold optical hyperparametric oscillations\nin a high-Q fluorite whispering gallery mode resonator. The oscillations\nresult from the resonantly enhanced four-wave mixing occurring due\nto Kerr nonlinearity of the material. We demonstrate that, because\nof the narrow bandwidth of the resonator modes as well as the high\nefficiency of the resonant frequency conversion, the oscillations\nproduce stable narrow-band beat-note of the Pump, Signal, and idler\nwaves. A theoretical model for this process is described.

Quantum state reconstruction of spectral field modes: Homodyne and resonator detection schemes
Physical Review A, 2013Co-Authors: Felippe A. S. Barbosa, Alessandro S. Villar, Claude Fabre, Paulo Nussenzveig, A. S. Coelho, Katiuscia N. Cassemiro, Marcelo MartinelliAbstract:We revisit the problem of quantum state reconstruction of light beams from the photocurrent quantum noise. As is well-known, but often overlooked, two longitudinal field modes contribute to each spectral component of the photocurrent (sideband modes). We show that spectral homodyne detection is intrinsically incapable of providing all the information needed for the full reconstruction of the two-mode spectral quantum state. Such a limitation is overcome by the technique of resonator detection. A detailed theoretical description and comparison of both methods is presented, as well as an experiment to measure the six-mode quantum state of Pump-Signal-idler beams of an optical parametric oscillator above the oscillation threshold.

Continuous-Variable Measurements of Non-Classical Light
Frontiers in Optics 2012 Laser Science XXVIII, 2012Co-Authors: Felippe F. Barbosa, Alessandro S. Villar, Marcelo Martinelli, Claude Fabre, A. S. Coelho, Katiuscia N. Cassemiro, Paulo NussenzveigAbstract:In recent years we have investigated Pump-Signal-idler entanglement in the above-threshold optical parametric oscillator. Spectral homodyne-type detection probes two sidebands at a given analysis frequency per beam. Hexapartite entanglement is observed.

Conference on Coherence and Quantum Optics, 2007Co-Authors: Katiuscia N. Cassemiro, Alessandro S. Villar, Marcelo Martinelli, P. Valente, Paulo NussenzveigAbstract:We generated bright entangled beams in an optical parametric oscillator, operating above threshold. Tripartite Pump-Signal-idler entanglement, all with different frequencies, was also predicted and three-color quantum correlations already measured.
