Structured light under turbulence
Guilherme S. Barros, Lucas C. Céleri, Antonio Zelaquett Khoury +3
Structured light has emerged as a promising resource for high-capacity and secure free-space optical communication, where atmospheric turbulence remains a major source of signal de…
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…
Optimal beam displacement measurements using high-order structured light modes
A. L. S. Santos Junior, J. C. de Carvalho Junior, M. Gil de Oliveira +4
We develop a novel technique to measure small angular and lateral displacements of structured light beams. The technique relies on using high-order Hermite-Gaussian (HG) and Laguer…
