Surface dark solitons in nonlocal nonlinear media

By XingHui Gao, Luohong Zhou, ZhenJun Yang, Xuekai Ma, Daquan Lu and Wei Hu


We predict the existence of surface dark solitons at the interface between a self-defocusing nonlocal nonlinear medium and a linear medium. The fundamental and higher-order surface dark solitons can exist when the linear refractive index of the self-defocusing media is much larger than that of the linear media. The fundamental solitons are stable and the stabilities of higher-order solitons depend on both nonlocality degree and propagation constant.Comment: 4 pages, 4 figure
