摘要：We investigate the formation and propagation of the Thirring spatial optical solitons in asymmetric quantum wells (QWs). By virtue of the quantum interference effect, the cross-phase modulation (XPM) can be enhanced greatly while the self-phase modulation and linear absorption are well suppressed with proper system parameters. Diffraction of the probe fields can be well balanced by the enhanced XPM alone, which results in their stationary propagation and the formation of Thirring vector optical solitons. In comparison with traditional vector optical solitons, such Thirring spatial optical solitons generated in the QWs can be of various widths and peak powers, implying their more prospective applications in optical communications and optical information processing.
