Abstract
The recently discovered pure-quartic solitons, arising from the interaction of quartic dispersion and Kerr nonlinearity, open the door to unexplored soliton regimes and ultrafast laser science. Here, we report a general analysis of the dispersion and nonlinear properties necessary to observe pure-quartic solitons in optical platforms. We apply this analysis, in combination with numerical calculations, to the design of pure-quartic soliton supporting microstructured optical fibers. The designs presented here, which have realistic fabrication tolerances, support unperturbed pure-quartic soliton propagation providing access to an unmatched platform to study novel soliton physics.
Highlights
Pure-quartic solitons (PQSs) are a novel class of solitary optical waves that arise from the interaction of negative fourth-order dispersion (FOD) and self-phase modulation (SPM) [1]
We focus our attention in a particular microstructured optical fibers (MOFs) design and demonstrate that, consistent with the analytic results from Section 2, it can support the propagation of PQSs using numerical solutions of the generalized nonlinear Schrödinger equation (NLSE) [1]
In this paper we aimed to provide the community with a rigorous understanding of the physical origin of PQSs, as well as a set of design rules for practical optical platforms suitable to observe this physical phenomenon
Summary
Pure-quartic solitons (PQSs) are a novel class of solitary optical waves that arise from the interaction of negative fourth-order dispersion (FOD) and self-phase modulation (SPM) [1]. Some of us demonstrated experimentally the existence of PQSs in a dispersion-engineered slow-light silicon photonic crystal waveguide (PhC-wg) [1] In this nanophotonic platform, the FOD effect was strongly dominant over all the other orders of dispersion at wavelengths centered around λ0 = 1550 nm and for pulse durations T0 ≈ 0.8 ps, across a bandwidth of approximately 4 − 5 nm. The FOD effect was strongly dominant over all the other orders of dispersion at wavelengths centered around λ0 = 1550 nm and for pulse durations T0 ≈ 0.8 ps, across a bandwidth of approximately 4 − 5 nm This strong FOD was balanced by the slow-light enhanced SPM in the silicon PhC-wg giving rise to PQSs in a few hundred microns waveguide. We study a realizable designs in detail and characterize its performance for PQS propagation by providing nonlinear Schrödinger equation (NLSE) simulations
