Soliton-radiation trapping in gas-filled photonic crystal fibers

TL;DR

This paper introduces a novel optical trapping method in gas-filled photonic crystal fibers where a soliton traps and oscillates with radiation via cross phase modulation, avoiding Raman and plasma effects.

Contribution

It presents a new trapping technique using soliton-radiation interaction in hollow-core fibers, expanding control over ultrashort pulse dynamics without Raman or plasma influences.

Findings

Demonstrates trapping of ultrashort radiation by a soliton

Shows periodic oscillation of trapped radiation due to shock effects

Proposes a Raman- and plasma-free trapping mechanism

Abstract

We propose an optical trapping technique in which a fundamental soliton traps an ultrashort small amplitude radiation in a symmetric hollow-core photonic crystal fiber filled with a noble gas, preventing its dispersion. The system is Raman- and plasma-free. Trapping is due to the cross phase modulation effect between the two pulses. The trapped radiation inside the soliton-induced potential will oscillate periodically due to the shock effect, similar to the motion of a mechanical pendulum.
