Can Light Cross a Singularity? Exact Solutions from Analogue Gravity
Juan Manuel Paez, Franco Fiorini, Santiago M. Hernández
Using a simple spacetime hosting a strong curvature naked singularity, we employ an analogue gravity model to study electromagnetic fields in this background. We find exact solutio…
Shedding Light on Naked Singularities
Franco Fiorini, Santiago Hernandez, Juan Manuel Paez
Electromagnetic waves propagating in the background provided by a spacetime hosting a strong curvature, naked singularity, are fully studied. The analysis is performed not only in…
Soliton generation through temporal reflection in media with a frequency-dependent nonlinearity
Lucas N. Gutierrez, Pablo I. Fierens, Diego F. Grosz +1
We demonstrate that the temporal reflection of a weak dispersive pulse on a soliton in media with a frequency-dependent nonlinearity leads to the generation of new solitons, whose…
Exact results on analogue gravity in optical Plebanski-Tamm media
Franco Fiorini, Santiago M. Hernandez, Edith L. Losada
Exact results concerning ray-tracing methods in Plebanski-Tamm media are derived. In particular, Hamilton equations describing the propagation of quasi-plane wave electromagnetic f…
A simple approach to the quantum theory of nonlinear fiber optics
J. Bonetti, A. D. Sánchez, S. M. Hernandez +1
We put forth an approach to obtain a quantum master equation for the propagation of light in nonlinear fiber optics by relying on simple quantum pictures of the processes (linear a…
A frequency-coded QKD scheme with an extension to qu-quarts
J. Bonetti, S. M. Hernandez, D. F. Grosz
We propose a novel scheme to implement the BB84 quantum key distribution (QKD) protocol in optical fibers based on a quantum frequency-translation (QFT) process. Unlike conventiona…
A geometrical view of scalar modulation instability
S. M. Hernandez, P. I. Fierens, J. Bonetti +2
We present a novel approach to the analysis of a full model of scalar modulation instability (MI) by means of a simple geometrical description in the power vs. frequency plane. Thi…
Analytical study of coherence in seeded modulation instability
J. Bonetti, S. M. Hernandez, P. I. Fierens +1
We derive analytical expressions for the coherence in the onset of modulation instability, in excellent agreement with thorough numerical simulations. As usual, we start by a linea…
Low-power Mid-IR Supercontinuum and Rogue Wave Generation in Chalcogenide Waveguides
Santiago M. Hernandez, Pablo I. Fierens, Juan Bonetti +1
We present numerical results of supercontinuum (SC) generation in the mid-IR spectral region, specifically addressing the molecular fingerprint window ranging from 2.5 to 25 um. By…
On the effect of self-steepening in modulation instability
Santiago M. Hernandez, Pablo I. Fierens, Juan Bonetti +1
We revisit the problem of modulation instability (MI) in optical fibers, including higher-order dispersion terms, self-steepening, and Raman response. We derive expressions for the…
