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…
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…
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…
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…
