Non-orthogonal Transformations of Structured Light Using Ellipticity-Dependent Ince-Gaussian Modes
Dayver Daza-Salgado, Edgar Medina-Segura, Carmelo Rosales-Guzmán
The Ince-Gaussian modes form a complete set of solutions to the paraxial wave equation parametrized by an ellipticity parameter ε, enabling a continuous transition between Laguerre…
A Higher-Order Poincaré Ellipsoid representation for elliptical vector beams
Dayver Daza-Salgado, Edgar Medina-Segura, Valeria Rodriguez-Fajardo +2
The Higher-Order Poincaré Sphere (HOPS) provides a powerful geometrical tool for representing vector beams as points on the surface of a unitary sphere. Since a particular position…
Generalized Elliptical Vector modes
Xiao-Bo Hu, Chen-Yu Chen, Qi-Yao Yuan +3
The strong coupling between the spatial and polarisation degrees of freedom (DoF) in vector modes enables a diverse array of exotic, inhomogeneous polarisation distributions throug…
Emulating a quantum Maxwell's demon with non-separable structured light
Edgar Medina-Segura, Paola C. Obando, Light Mkhumbuza +6
Maxwell's demon (MD) has proven an instructive vehicle by which to explore the relationship between information theory and thermodynamics, fueling the possibility of information dr…
Structured Lightś Applications: A perspective
Carmelo Rosales-Guzmán, Valeria Rodriguez-Fajardo
For the past few decades, structured light has been gaining popularity across various research fields. Its fascinating properties have been exploited for both previously unforeseen…
Experimental realization of vortex and vectorial vortex Pearcey-Gauss Beams
Valeria Rodríguez-Fajardo, Gabriela Flores-Cova, Carmelo Rosales-Guzmán +1
In this manuscript, we put forward two new types of structured light beams, the vortex Pearcey-Gauss (VPeG) beam, with a homogeneous polarisation distribution, and the vector vorte…
Hermite-Laguerre-Gaussian Vector Modes
Edgar Medina-Segura, Leonardo Miranda-Culin, Benjamin Perez-García +2
Vector modes are well-defined field distributions with spatially varying polarisation states, rendering them irreducible to the product of a single spatial mode and a single polari…
Experimental generation of cylindrical vector modes via an astigmatic mode converter
Tatiana Román-Valenzuela, Valeria Rodríguez-Fajardo, Xiao Bo-Hu +1
In this work, we propose and demonstrate experimentally a compact technique for the generation of cylindrical vector beams, based on a Michelson interferometer and a -astigmatic…
Generation of super-stable vector modes using on-axis complex-amplitude modulation
Valeria Rodríguez-Fajardo, Fernanda Arvizu, Dayver Daza-Salgado +2
In this manuscript, we propose the generation of complex vector beams with high quality and stability based on a novel approach that relies on the combination of two techniques tha…
Violation of Bell's inequality for Mathieu-Gauss vector modes
Edgar Medina-Segura, Francisco I. Mecillas-Hernandez, Thomas Konrad +2
Vector beams display varying polarisation over planes transversal to their direction of propagation. The variation of polarisation implies that the electric field cannot be express…
Vectorial Helico-Conical beams
Edgar Medina-Segura, Leonardo Miranda-Culin, Valeria Rodríguez-Fajardo +2
In this work, we propose and demonstrate experimentally a new family of vector beams, the Helico-Conical Vector Beams (HCVB), whose spatial degree of freedom is encoded in the Heli…
Holographic tool kit for optical communication beyond orbital angular momentum
Abderrahmen Trichili, Carmelo Rosales-Guzmán, Angela Dudley +4
Mode division multiplexing (MDM) is mooted as a technology to address future bandwidth issues, and has been successfully demonstrated in free space using spatial modes with orbital…
