Soliton solutions and self-steepening in the photon-conserving nonlinear Schrödinger equation
(Taylor & Francis Ltd, 2020-12)
We have recently introduced a new modeling equation for the propagation of pulses in optical waveguides, the photon-conserving Nonlinear Schrödinger Equation (pcNLSE) which, unlike the canonical NLSE, guarantees strict ...
Measuring self-steepening with the photon-conserving nonlinear Schrödinger equation
(Optical Society of America, 2020-08)
We propose an original, simple, and direct method to measure self-steepening (SS) in nonlinear waveguides. Our proposal is based on results derived from the recently introduced photon-conserving nonlinear Schrödinger ...
Photon-conserving generalized nonlinear Schrödinger equation for frequency-dependent nonlinearities
(Optical Society of America, 2020-01)
Pulse propagation in nonlinear waveguides is most frequently modeled by resorting to the generalized nonlinear Schrödinger equation (GNLSE). In recent times, exciting new materials with peculiar nonlinear properties, such ...
Modified nonlinear Schrödinger equation for frequency-dependent nonlinear profiles of arbitrary sign
(Optical Society of America, 2019-10)
In recent times, materials exhibiting frequency-dependent optical nonlinearities, such as nanoparticle-doped glasses and other metamaterials, have gathered significant interest. The simulation of the propagation of intense ...
Revisiting Soliton Dynamics in Fiber Optics under Strict Photon-Number Conservation
(Institute of Electrical and Electronics Engineers, 2021-04)
We revisit the complex interplay between the Raman-induced frequency shift (RIFS) and the effect of self-steepening (SS) in the propagation of solitons, and in the framework of an equation that ensures strict conservation ...

In recent times, materials exhibiting frequency-dependent optical nonlinearities, such as nanoparticle-doped glasses and other metamaterials, have gathered significant interest. The simulation of the propagation of intense ...
Quantum Noise in Fibers with Arbitrary Nonlinear Profiles
(American Physical Society, 2021-05)
In this Letter we introduce a novel equation addressing the effect of quantum noise in optical fibers with arbitrary frequency-dependent nonlinear profiles. To the best of our knowledge, such an endeavor has not been ...
Modulation instability in waveguides with an arbitrary frequency-dependent nonlinear coefficient
(Optical Society of America, 2020-05)
In this Letter, we present, for the first time, to the best of our knowledge, the modulation instability (MI) gain spectrum of waveguides with an arbitrary frequency-dependent nonlinear coefficient ensuring strict energy ...
Simple model for the nonlinear optical response of dimer-doped waveguides
(Optical Society of America, 2021-01)
We put forth a simple model that allows to obtain the nonlinear coefficient of a waveguide doped with dimers of Ag and Au, and study its unique nonlinear optical properties through the recently introduced photon-conserving ...
Modulation instability in waveguides doped with anisotropic nanoparticles
(Optical Society of America, 2020-06)
We exploit the anisotropic plasmonic behavior of gold nanorods (AuNRs) to obtain a waveguide with a nonlinear coefficient dependent on both the frequency and polarization of incident light. The optical properties of the ...
