Goos-Hänchen and Imbert-Fedorov shifts for paraxial X-Waves
Marco Ornigotti, Andrea Aiello, Claudio Conti
We present a theoretical analysis for the \GH and \IF shifts experienced by an X-wave upon reflection from a dielectric interface. We show that the temporal chirp, as well as the b…
Cylindrically polarized Bessel-Gauss beams
Daena Madhi, Marco Ornigotti, Andrea Aiello
We present a study of radially and azimuthally polarized Bessel-Gauss beams in both the paraxial and nonparaxial regimes. We discuss the validity of the paraxial approximation and…
The Faddeev-Popov Method Demystified
Marco Ornigotti, Andrea Aiello
We discuss how to implement the Legendre transform using the Faddeev-Popov method of Quantum Field Theory. By doing this, we provide an alternate way to understand the essence of t…
Radially Self-Accelerating Beams
Christian Vetter, Toni Eichelkraut, Marco Ornigotti +2
We report on optical non-paraxial beams that exhibit a self-accelerating behavior in radial direction. Our theory shows that those beams are solutions to the full scalar Helmholtz…
Generalized Bessel beams with two indices
Marco Ornigotti, Andrea Aiello
We report on a new class of exact solutions of the scalar Helmholtz equation obtained by carefully engineering the form of the angular spectrum of a Bessel beam. We consider in par…
Quasi PT-symmetry in passive photonic lattices
Marco Ornigotti, Alexander Szameit
The concept of quasi-PT symmetry in optical wave guiding system is elaborated by comparing the evolution dynamics of a PT-symmetric directional coupler and a passive directional co…
