Non-collinear interaction of photons with orbital angular momentum

Thomas Roger, Julius J. F. Heitz, Ewan. M. Wright +1

We elucidate the consequences of a phase-matching theory that describes second-harmonic generation of two non-collinear incident light beams that carry orbital angular momentum (OA…

Negative frequencies get real: a missing puzzle piece in nonlinear optics

Matteo Conforti, Andrea Marini, Daniele Faccio +1

Motivated by recent experimental results, we demonstrate that the ubiquitous pulse propagation equation based on a single generalized nonlinear Schroedinger equation is incomplete…

Negative-frequency dispersive wave generation in quadratic media

Matteo Conforti, Niclas Westerberg, Fabio Baronio +2

We show that the extremely blue-shifted dispersive wave emitted in Kerr media owing to the coupling with the negative-frequency branch [Phys. Rev. Lett. {\bf 108}, 253901 (2012)] c…

High-energy, shock-front assisted resonant radiation in the normal dispersion regime

Thomas Roger, Mohammed F. Saleh, Samudra Roy +3

We present a simple yet effective theory that predicts the existence of resonant radiation bands in the deep normal group velocity dispersion region of a medium, even in absence of…

Nonlinear imaging and 3D-mapping of terahertz fields with Kerr media

Matteo Clerici, Daniele Faccio, Lucia Caspani +6

We investigate the spatially and temporally resolved four-wave mixing of terahertz fields and optical pulses in large band-gap dielectrics, such as diamond. We show that it is poss…

Entanglement generation in relativistic cavity motion

David Edward Bruschi, Jorma Louko, D. Faccio

We analyse particle creation and mode mixing for a quantum field in an accelerated cavity, assuming small accelerations but allowing arbitrary velocities, travel times and travel d…
