Self-similar propagation of optical pulses in fibers with positive quartic dispersion
Published 2020We study the propagation of ultrashort pulses in optical fiber with gain and positive (or normal) quartic dispersion by self-similarity analysis of the modified nonlinear Schrödinger equation. We find an exact asymptotic ...Open AccessArticle -
Generalized dispersion Kerr solitons
Published 2020We report a continuum of pulse-like soliton solutions to the generalized nonlinear Schr ̈odinger equation with both quadratic and quartic dispersion and a Kerr nonlinearity. We show that the well-known nonlinear Schr ...Open AccessArticle -
Stationary and Dynamical Properties of Pure-Quartic Solitons
Published 2019We numerically solve a generalized nonlinear Schrödinger equation and find a family of pure-quartic solitons, existing through a balance of positive Kerr nonlinearity and negative quartic dispersion. These solitons have ...Open AccessArticle -
Generalized self-similar propagation and amplification of optical pulses in nonlinear media with high-order normal dispersion
Published 2021We investigate theoretically and numerically the self-similar propagation of optical pulses in the presence of gain, positive Kerr nonlinearity and positive (i.e. normal) dispersion of even order m. Starting from a modified ...Open AccessArticle -
Scenario modelling of biomass usage in the Australian electricity grid
Published 2022Responding to the global crises - Covid19 and climate change - governments around the world are formulating green recovery plans to stimulate economic growth, boost clean energy technologies and cut emissions. Potential ...Article
