Trapping microparticles in a structured dark focus
F. Almeida, I. Sousa, O. Kremer +5
We experimentally demonstrate stable trapping and controlled manipulation of silica microspheres in a structured optical beam consisting of a dark focus surrounded by light in all…
Quantum and classical separability of spin-orbit laser modes
L. J. Pereira, A. Z. Khoury, K. Dechoum
In this work we investigate the quantum noise properties of polarization vortices in connection with an intensity based Clauser-Horne-Shimony-Holt inequality for their spin-orbit s…
Semiclassical Wigner distribution for two-mode entangled state
K. Dechoum, M. D. Hahn, R. O. Vallejos +1
We derive the steady state solution of the Fokker-Planck equation that describes the dynamics of the nondegenerate optical parametric oscillator in the truncated Wigner representat…
Semiclassical Wigner distribution for two-mode entangled state generated by an optical parametric oscillator
K. Dechoum, M. D. Hahn, A. Z. Khoury +1
We derive the steady state solution of the Fokker-Planck equation that describes the dynamics of the nondegenerate optical parametric oscillator in the truncated Wigner representat…
Quantum analysis of the nondegenerate optical parametric oscillator with injected signal
B. Coutinho dos Santos, K. Dechoum, A. Z. Khoury +2
In this paper we study the nondegenerate optical parametric oscillator with injected signal, both analytically and numerically. We develop a perturbation approach which allows us t…
