Propagation-Invariant Transmission Eigenmodes in Weakly Scattering Media
J. C Osorio-Tascon, P. A. Quinto-Su
Propagation-invariant beams (PIBs) with annular angular spectra preserve their transverse intensity structure over extended propagation distances. Here, we investigate whether scat…
Optical Möbius Snails
Qiang Wang, Pedro A. Quinto-Su, Xi Xie +3
The exploration of topological states has emerged as a vibrant frontier across diverse physical systems. Among these, the Möbius strip stands out as a canonical structure that has…
Errors in single pixel photography emerging from light collection limits by the bucket detector
Dennis Scheidt, Pedro A. Quinto-Su
In single pixel photography an image is sampled with a programmable optical element like a digital micromirror array or a spatial light modulator that can project an orthogonal bas…
Shaping the angular spectrum of a Bessel beam to enhance light transfer through dynamic strongly-scattering media
Dennis Scheidt, Alejandro Vasquez Arzola, Pedro Antonio Quinto-Su
We prepare a quasi-non-diffracting Bessel beam defined within an annular angular spectrum with a spatial light modulator. The beam propagates though a strongly scattering media and…
Interferometric measurement of arbitrary propagating vector beams that are tightly focused
Pedro A. Quinto-Su
In this work we demonstrate a simple setup to generate and measure arbitrary vector beams that are tightly focused. The vector beams are created with a spatial light modulator and…
Simple computer program to calculate arbitrary tightly focused (propagating and evanescent) vector light fields
Isael Herrera, Pedro A. Quinto-Su
In this work we present a simple code to calculate tightly focused vectorial light fields (propagating and evanescent) generated by input fields that have arbitrary amplitude, phas…
Measurement of a wavelength sized optical vortex knot
I. A. Herrera-Hernández, C. A. Mojica-Casique, P. A. Quinto-Su
In the past decade, optical vortex knots with axial dimensions on the order of wavelengths () have been implemented in the laboratory. However, many potential applic…
Measurement of structured tightly focused vector beams with classical interferometry
Isael A. Herrera-Hernández, Pedro A. Quinto-Su
We report the first measurement with no approximations of the full field of tightly focused vector beams (NA up to ) across areas of . Prior to focusing, the…
Morphological properties of 2D symmetric Airy beams extracted from the stationary wave approximation
F. Camas-Aquino, P. A. Quinto-Su, R. Jáuregui
We explore the morphological properties of symmetric Airy beams in the paraxial and nonparaxial regimes. We consider a 2D electromagnetic realization with a single transverse compo…
Phase dependent vectorial current control in symmetric noisy optical ratchets
Magda G. Sánchez-Sánchez, Roberto de J. León-Montiel, Pedro A. Quinto-Su
In this work we demonstrate single microparticle transport in a symmetric noisy optical ratchet where each potential is a low power ( mW) three dimensional trap. The optical…
Noise-Enabled Optical Ratchets
Roberto de J. León-Montiel, Pedro A. Quinto-Su
In this work we demonstrate single microparticle transport enabled by noise in a one dimensional optical lattice with periodic symmetric potentials and a small constant external fo…
Transient trapping of two microparticles interacting with optical tweezers and cavitation bubbles
Viridiana Carmona-Sosa, Pedro A. Quinto-Su
In this work we show that two absorbing microbeads can briefly share the same optical trap. Optical forces pull the particles towards the waist of the trapping beam. However, once…
Natural focusing of symmetric Airy beams
R. Jauregui, P. A. Quinto-Su
In this work we study the natural focusing of Airy beams symmetric under reflection of the transverse coordinates. Following a recent proposal, their angular spectra depend on the…
