Adaptive Solitons
Yuchuan Chen, Jiacheng Zhao, Qiuran Zhu +1
Femtosecond laser pulses have incredible potential but still face some performance and stability issues. Here we discover a new nonlinear optical effect, frequency-comb-induced sti…
Towards polarization steganography
Valeria Tena-Piñon, Atefeh Akbarpour, Przemyslaw Litwin +6
We propose and experimentally demonstrate a polarization--based steganographic scheme using partially polarized vector beams. In our approach, the spatially dependent polarization…
Orbital angular momentum of spatiotemporal vortices: a ray-mechanical analogy
Sophie Vo, Konstantin Y. Bliokh, Miguel A. Alonso
Spatiotemporal vortex pulses (STVPs) are wavepackets that carry transverse orbital angular momentum (OAM), whose proper quantification has been the subject of recent debate. In thi…
Flying focus with arbitrary directionality for spatiotemporal control of laser pulses
Sida Cao, Devdigvijay Singh, Lavonne S. Mack +2
Flying focus techniques produce laser pulses whose focal points travel at arbitrary, controllable velocities. While this flexibility can enhance a broad range of laser-based applic…
Source Wavefront Generation for a Non-Interferometric Reconfigurable Null Test using a Photonic Lantern
Nikolas Romer, Jannick P. Rolland
A method is presented to use a fiber-optic device known as a photonic lantern to generate a reconfigurable custom wavefront for a null test of spherical, aspheric, and freeform opt…
An experimental technique for measuring radial coherence
Radhika Prasad, Nilakshi Senapati, Suman Karan +4
Coherence refers to correlations between field vibrations at two separate points in degrees of freedom such as space, time, and polarisation. In the context of space, coherence the…
Robust purely optical signatures of Floquet states in laser-dressed crystals
Vishal Tiwari, Roman Korol, Ignacio Franco
Strong light-matter interactions can create non-equilibrium materials with on-demand novel functionalities. For periodically driven solids, the Floquet theorem provides the natural…
Coherent frequency combs from electrons colliding with a laser pulse
Michael J. Quin, Antonino Di Piazza, Matteo Tamburini
Highly coherent and powerful light sources capable of generating soft x-ray frequency combs are essential for high precision measurements and rigorous tests of fundamental physics.…
Computational refocusing in phase-resolved confocal microscopy
Martin Schnell, Melanie King, Sam Buercklin +3
We demonstrate numerical refocusing in coherent confocal laser scanning microscopy based on synthetic optical holography. This physics-based approach implements a computational pro…
Coherent control of an optical tweezer phonon laser
Kai Zhang, Kewen Xiao, Danika Luntz-Martin +4
The creation and manipulation of coherence continues to capture the attention of scientists and engineers. The optical laser is a canonical example of a system that, in principle,…
Ray and caustic structure of Ince-Gauss beams
Rodrigo Gutiérrez-Cuevas, Mark R. Dennis, Miguel A. Alonso
The Ince-Gauss beams, separable in elliptic coordinates, are studied through a ray-optical approach. Their ray structure can be represented over a ray-Poincaré sphere by generalize…
Periodic skyrmionic textures via conformal cartographic projections
David Marco, Isael Herrera, Sophie Brasselet +1
We find periodic skyrmionic textures via conformal cartographic projections that map either an entire spherical parameter space or a hemisphere onto every regular polygon that prov…
Vectorial phase retrieval in super-resolution polarization microscopy
Rodrigo Gutiérrez-Cuevas, Luis A. Alemán-Castañeda, Isael Herrera +2
In single molecule orientation localization microscopy, valuable information about the orientation and longitudinal position of each molecule is often encoded in the shape of the p…
Experimental realization of supergrowing fields
Sethuraj K. R., Tathagata Karmakar, S. A. Wadood +2
Supergrowth refers to the local amplitude growth rate of a signal being faster than its fastest Fourier mode. In contrast, superoscillation pertains to the variation of the phase.…

Andrew N. Jordan, John C. Howell
We establish fundamental bounds on subwavelength resolution for the radar ranging problem, ``super radar''. Information theoretical metrics are applied to probe the resolution limi…
Supergrowth and sub-wavelength object imaging
Tathagata Karmakar, Abhishek Chakraborty, A. Nick Vamivakas +1
We further develop the concept of supergrowth [Jordan, Quantum Stud.: Math. Found. , 285-292 (2020)], a phenomenon complementary to superoscillation, defined as the loc…
Floquet theory and computational method for the optical absorption of laser-dressed solids
Vishal Tiwari, Bing Gu, Ignacio Franco
Recent advances in laser technology now enable engineering the electronic structure of matter through strong light-matter interactions. However, the effective physicochemical prope…
Hybrid THz architectures for molecular polaritonics
Ahmed Jaber, Michael Reitz, Avinash Singh +7
Physical and chemical properties of materials can be modified by a resonant optical mode. Such recent demonstrations have mostly relied on a planar cavity geometry, others have rel…
