Twisted Gaussian Schell States in Quantum Optics: Twist-Assisted Nonclassicality and Entanglement
Fabricio Toscano, G. Cañas, A. Z. Khoury +2
We introduce the Twisted Gaussian Schell (TGS) state, a two-mode mixed Gaussian state defined as the quantum-optical analog of the Twisted Gaussian Schell-model beam of classical p…
All-optical saddle trap as a platform for mesoscopic quantum experiments
Pedro V. Paraguassú, Luca Abrahão, Daniel Tandeitnik +3
We investigate the quantum dynamics of a levitated nanoparticle in a structured light rotating saddle-like optical potential consisting of a superposition of Gaussian and Laguerre-…
Experimental Investigation of Twist Conservation in Nonlinear Optical Three-Wave Mixing
Gustavo H. dos Santos, André L. S. Santos Junior, Marcos Gil de Oliveira +7
We conduct an experimental investigation into the conservation of the twist phase in Twisted Gaussian Schell Model (TGSM) beams during both up- and down-conversion three-wave mixin…
Anomalous Second Harmonic Generation of Twisted Gaussian Schell Model Beams
M. Gil de Oliveira, A. L. S. Santos Junior, A. C. Barbosa +6
We investigate theoretically and experimentally the optical second harmonic generation (SHG) with a twisted Gaussian Schell model (TGSM) beam as the fundamental field. We use Type-…
Resonance of Vector Vortex Beams in a Triangular Optical Cavity
L. M. Rodrigues, L. Marques Fagundes, D. C. Salles +5
We experimentally demonstrate resonance of first-order vector vortex beams (VVB) with a triangular optical cavity. We also show that, due to their symmetry properties, the VVBs com…
Observation of triangular-lattice pattern in nonlinear wave mixing with optical vortices
B. Pinheiro da Silva, G. H. dos Santos, A. G. de Oliveira +8
A triangular-lattice pattern is observed in light beams resulting from the spatial cross modulation between an optical vortex and a triangular shaped beam undergoing parametric int…
Optical Trapping in a Dark Focus
Bruno Melo, Igor Brandão, B. Pinheiro da Silva +3
The superposition of a Gaussian mode and a Laguerre-Gauss mode with generates the so-called bottle beam: a dark focus surrounded by a bright region. In this paper,…
