Frequency comb formation in doubly resonant second-harmonic generation
F. Leo, T. Hansson, I. Ricciardi +4
We theoretically study the generation of optical frequency combs and corresponding pulse trains in doubly resonant intracavity second-harmonic generation (SHG). We find that, despi…
Single envelope equation modelling of multi-octave comb arrays in microresonators with quadratic and cubic nonlinearity
T. Hansson, F. Leo, M. Erkintalo +5
We numerically study, by means of the single envelope equation, the generation of optical frequency combs ranging from the visible to the mid-infrared spectral regions in resonator…
Origin and stability of dark pulse Kerr combs in normal dispersion resonators
Pedro Parra-Rivas, Damia Gomila, Edgar Knobloch +2
We analyze dark pulse Kerr frequency combs in optical resonators with normal group-velocity dispersion using the Lugiato-Lefever model. We show that in the time domain these corres…
Observation of Spatiotemporal Chaos Induced by a Cavity Soliton in a Fiber Ring Resonator
Miles Anderson, Francois Leo, Stephane Coen +2
We report on the experimental observation of temporal cavity soliton destabilization via spatiotemporal chaos in a coherently-driven optical fiber ring resonator. Numerical simulat…
Controlled merging and annihilation of localized dissipative structures in an AC-driven damped nonlinear Schrödinger system
Jae K. Jang, Miro Erkintalo, Kathy Luo +3
We report studies of controlled interactions of localized dissipative structures in a system described by the AC-driven damped nonlinear Schrödinger equation. Extensive numerical s…
Analysis of Cascaded Brillouin Scattering in Optical Fibres
Neil G. R. Broderick, Stephane X. Coen
Cascaded Brillouin scattering is increasingly becoming of interest in many areas of pho- tonics (e.g. see [1] and [2]) and has been studied experimentally by many groups. In gain a…
