DARK SPATIAL OPTICAL SOLITON AND SOLITON-INDUCED ELEXIBLE WAVEGUIDE IN C60 SOLUTION
C60溶液中的暗空间光孤子及其诱导的柔性光波导

The phenomena of dark spatial optical soliton and soliton-induced flexible optical wave-guide have been observed, which are induced by thermal self-defocusing effect of Ar+ laser beam in C60-toluene solution. The numerical simulations of the formation process of dark spatial soliton using the nonlinear Schr?dinger equation are consistent with the experimental results.
