Talbot interference of whispering gallery modes
Matias Eriksson, Benjamin A. Stickler, Robert Fickler
The Talbot self-imaging phenomenon is a fundamental interference effect that is natural to all waves with a periodic structure. We theoretically and experimentally study the Talbot…
Higher-order Poincaré Spheres and Spatio-Spectral Poincaré Beams
Robert Fickler, Lea Kopf, Marco Ornigotti
The study of fundamental optics effects has been stimulated through the increasing ability to structure light in all its degrees of freedom (DOFs) in sophisticated but simple exper…
Generalized angle-orbital-angular-momentum Talbot effect and modulo mode sorting
Jianqi Hu, Matias Eriksson, Sylvain Gigan +1
The Talbot effect describes periodic revivals of field patterns and is ubiquitous across wave systems. In optics, it is mostly known for its manifestations in space and time, but i…
Phase-Matched Second-Harmonic Generation from Metasurfaces Inside Multipass Cells
Madona Mekhael, Timo Stolt, Anna Vesala +4
We demonstrate a simple and scalable approach to increase conversion efficiencies of nonlinear metasurfaces by incorporating them into multipass cells and by letting the pump beam…
High-order aberrations of vortex constellations
Rafael Barros, Subhajit Bej, Markus Hiekkamäki +2
When reflected from an interface, a laser beam generally drifts and tilts away from the path predicted by ray optics, an intriguing consequence of its finite transverse extent. Suc…
Electromagnetic Angular Momentum
Masud Mansuripur
This article was published as Sec.5 of the "Roadmap on Structured Light" in Journal of Optics 19 (2017) 013001. Section 5 describes the essential elements of the classical theory o…
