| 英文摘要 | Stochastic resonance (sr) induced by the signal modulation is investigated, by introducing the signal-modulated gain into a single-mode laser system. using the linear approximation method, we detailedly calculate the signal-to-noise ratio (snr) of a gain-noise model of the single-mode laser, taking the cross-correlation between the quantum noise and pump noise into account. we find that, sr appears in the dependence of the snr on the intensities of the quantum and the pump noises when the correlation coefficient between both the noises is negative; moreover, when the cross-correlation between the two noises is strongly negative, sr exhibits a resonance and a suppression versus the gain coefficient, meanwhile, the single-peaked sr and multi-peaked sr occur in the behaviors of the snr as functions of the loss coefficient and the deterministic steady-state intensity.
