Wavefront sensing based on the inverted Hartmann sensor
Job Mendoza-Hernandez, Dorilian Lopez-Mago
The classic Hartmann test consists of an array of holes to reconstruct the wavefront from the local deviation of each focal spot, and Shack-Hartmann sensor improved that with an ar…
Cylindrical vector beam generator using a two-element interferometer
Job Mendoza-Hernandez, Manuel F. Ferrer-Garcia, Jorge Arturo Rojas-Santana +1
We realize a robust and compact cylindrical vector beam generator which consists of a simple two-element interferometer composed of a beam displacer and a cube beamsplitter. The in…
Generation of light beams with custom orbital angular momentum and tunable transverse intensity symmetries
Job Mendoza-Hernández, Mateusz Szatkowski, Manuel F. Ferrer-Garcia +2
We introduce a novel and simple modulation technique to tailor optical beams with a customized amount of orbital angular momentum (OAM). The technique is based on the modulation of…
Structured light beams constituted of incoming and outgoing waves
Job Mendoza-Hernández, Maximino Luis Arrroyo-Carrasco, Marcelo David Iturbe-Castillo +1
In the present work, we demonstrate that structured light beams are constituted by two traveling waves which transverse components are in opposite directions, that is, incoming and…
Observation of the full spiral spectrum of a light beam with single-pixel detection
Luis Jose Salazar-Serrano, Job Mendoza-Hernandez, Juan P. Torres
We demonstrate experimentally a simple and easy-to-use technique aimed at measuring the complex orbital angular momentum spectrum of an arbitrary optical field making use of just p…
