Ionization waves of arbitrary velocity driven by a flying focus

J. P. Palastro, D. Turnbull, S. -W. Bahk +5

A chirped laser pulse focused by a chromatic lens exhibits a dynamic, or "flying," focus in which the trajectory of the peak intensity decouples from the group velocity. In a mediu…

Poincaré sphere representation for spatially varying birefringence

Anthony Vella, Miguel A. Alonso

The Poincaré sphere is a graphical representation in a three-dimensional space for the polarization of light. Similarly, an optical element with spatially varying birefringence can…

Compressive Direct Imaging of a Billion-Dimensional Optical Phase-Space

Samuel H. Knarr, Daniel J. Lum, James Schneeloch +1

Optical phase-spaces represent fields of any spatial coherence, and are typically measured through phase-retrieval methods involving a computational inversion, interference, or a r…

Sorting photons by radial quantum number

Yiyu Zhou, Mohammad Mirhosseini, Dongzhi Fu +4

The Laguerre-Gaussian (LG) modes constitute a complete basis set for representing the transverse structure of a {paraxial} photon field in free space. Earlier workers have shown ho…

Perturbed Dissipative Solitons: A Variational Approach

Ambaresh Sahoo, Samudra Roy, Govind P. Agrawal

We adopt a variational technique to study the dynamics of perturbed dissipative solitons, whose evolution is governed by a Ginzburg--Landau equation (GLE). As a specific example of…

Generation of Caustics and Spatial Rogue Waves from Nonlinear Instability

Akbar Safari, Robert Fickler, Miles J. Padgett +1

Caustics are natural phenomena in which nature concentrates the energy of waves. Although, they are known mostly in optics, caustics are intrinsic to all wave phenomena. For exampl…

Optimization of Anisotropic Photonic Density of States for Raman Cooling

Yin-Chung Chen, Indronil Ghosh, André Schleife +2

Optical refrigeration of solids holds tremendous promise for applications in thermal management. It can be achieved through multiple mechanisms including inelastic anti-Stokes Bril…

Phase retrieval of an electron vortex beam using diffraction holography

Federico Venturi, Marco Campanini, Gian Carlo Gazzadi +6

In both light optics and electron optics, the amplitude of a wave scattered by an object is an observable that is usually recorded in the form of an intensity distribution in a rea…

Practical Advantages of Almost-Balanced-Weak-Values Metrological Techniques

Julián Martínez-Rincón, Zekai Chen, John C. Howell

Precision measurements of ultra-small linear velocities of one of the mirrors in a Michelson interferometer are performed using two different weak-values techniques. We show that t…

Custom-tailored spatial mode sorting by controlled random scattering

Robert Fickler, Manit Ginoya, Robert W. Boyd

The need to increase data transfer rates constitutes a key challenge in modern information-driven societies. Taking advantage of the transverse spatial modes of light to encode mor…
