Second-order moment equivalence of twisted Gaussian Schell model beams and orbital angular momentum eigenmodes
T. Ferreira, G. Santos, S. Ayala +5
We show that the covariance matrix of any cylindrically symmetric coherent orbital angular momentum (OAM) eigenmode with quantum number takes a universal form depending only…
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-…
Transmission of optical communication signals through ring core fiber using perfect vortex beams
Nelson Villalba, Cristóbal Melo, Sebastián Ayala +10
Orbital angular momentum can be used to implement high capacity data transmission systems that can be applied for classical and quantum communications. Here we experimentally study…
Partial coherence and coherence length in StimPDC
Gustavo Henrique dos Santos, Raphael César Souza Pimenta, Rafael de Morais Gomes +2
In parametric down conversion, a nonlinear crystal is pumped by a laser and spontaneous emission takes place in signal and idler modes according to the phase matching conditions. A…
Optimal conditions for multiplexing information into ring-core optical fibers
Santiago Rojas-Rojas, Gustavo Cañas, Gabriel Saavedra +3
In optical communications, space-division multiplexing is a promising strategy to augment the fiber network capacity. It relies on modern fiber designs that support the propagation…
