%0 Journal Article %T Soliton-radiation trapping in gas-filled photonic crystal fibers %A Mohammed F. Saleh %A Fabio Biancalana %J Physics %D 2013 %I arXiv %R 10.1103/PhysRevA.87.043807 %X 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. %U http://arxiv.org/abs/1301.5998v1
