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 ...
A Direct Method for the Simultaneous Estimation of Self-Steepening and the Fractional Raman Contribution in Fiber Optics
(Institute of Electrical and Electronics Engineers, 2021-06)
We propose an original, simple, and direct method for the simultaneous estimation of the self-steepening parameter and the fractional Raman contribution in fiber optics. Our proposal is based on the dependence of the ...
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 ...
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 ...
Narrowband and ultra-wideband modulation instability in nonlinear metamaterial waveguides
(Optical Society of America, 2020-11)
Waveguides based on metamaterials may exhibit strongly frequency-dependent nonlinearities. In this work, we focus on the phenomenon of modulation instability in this type of waveguide, departing from a new modeling equation ...
Anti-Stokes Raman gain enabled by modulation instability in mid-IR waveguides
(Optical Society of America, 2018-11)
The inclusion of self-steepening in the linear stability analysis of modulation instability (MI) leads to a powercutoff above which the MI gain vanishes. Under these conditions, MI in mid-IR waveguides is shown to give ...
