<title>Resonant light-light interaction in slab waveguides: angular filters and spectral hole burning</title>

Abstract

We consider the process of low-power light scattering by optical solitons in a slab waveguide with homogeneous and inhomogeneous refractive index core. We observe resonant reflection (Fano resonance) as well as resonant transmission of light by optical solitons at certain incident angles. The resonance position can be controlled experimentally by changing the soliton intensity and the relative frequency detuning between the soliton and the probe light beams.

Discrete breathers — Advances in theory and applications

“…Interactions between highly localized discrete solitons and propagating broad wavepackets have been recently studied in AlGaAs waveguide arrays [273,271]. Also, experimental setups for the direct observation of resonant wave scattering by DBs and associated spectral hole burning effects have been developed on the basis of optical waveguides [119,156], see next chapter.…”

“…Instead of computing the averaged transmission coefficient for the wavepacket, one may analyze the spectral characteristics of the transmitted and reflected waves. The resonant components will be filtered out from the transmitted (resonant reflection) and reflected (resonant transmission) wavepackets [156]. This mechanism is illustrated for the case of wavepacket scattering by the DNLS breather in Fig.…”

“…This would involve certain modifications in the corresponding model equations, more details can be found in Ref. [156].…”

“…Such a spectral hole burning effect opens a promising way for an experimental detection of the resonant reflection and transmission, e.g. by using nonlinear optical waveguides [156].…”
