TL;DR

This paper investigates how weak dispersive waves interact with trains of temporal solitons, revealing quasi-periodic reflection and transmission behaviors analogous to Fabry-Perot and Bragg resonators, through systematic numerical simulations.

Contribution

It demonstrates the emulation of Fabry-Perot and Bragg resonator behaviors using temporal optical solitons and analyzes their effects on dispersive wave scattering.

Findings

Reflection depends strongly on inter-soliton distance

Transmission and reflection coefficients show quasi-periodic patterns

Analogies with traditional optical resonators are established

Abstract

The scattering of weak dispersive waves (DW) on several equally spaced temporal solitons is studied. It is shown by systematic numerical simulations that the reflection of the DWs from the soliton trains strongly depends on the distance between the solitons. The dependence of the reflection and transmission coefficients on the inter-soliton distance and the frequency of the incident waves is studied in detail, revealing fascinating quasi-periodic behavior. The analogy between the observed nonlinear phenomena in temporal domain and usual Fabry-Perot and Bragg resonators is discussed.
