Coherence controlled soliton interactions
Ting-Sen Ku, Ming-Feng Shih, Andrey A. Sukhorukov +1
We demonstrate theoretically and subsequently observe in experiment a novel type of soliton interaction when a pair of closely spaced spatial optical solitons as a whole is made pa…
Spatial coherence singularities and incoherent vortex solitons
Kristian Motzek, Yuri S. Kivshar, Ming-Feng Shih +1
We study spatially localized optical vortices created by self-trapping of partially incoherent light with a phase dislocation in a biased photorefractive crystal. In a contrast to…
Partially incoherent optical vortices in self-focusing nonlinear media
Chien-Chung Jeng, Ming-Feng Shih, Kristian Motzek +1
We observe stable propagation of spatially localized single- and double-charge optical vortices in a self-focusing nonlinear medium. The vortices are created by self-trapping of pa…
Soliton transverse instabilities in anisotropic nonlocal self-focusing media
Kristian Motzek, Friedemann Kaiser, Wen-Hen Chu +2
We study, both theoretically and experimentally, the transverse modulational instability of spatial stripe solitons in anisotropic nonlocal photorefractive media. We demonstrate th…
