| Abstract: | A single-mode laser noise model driven by quadratic colored pump noise andbiased amplitude modulation signal is proposed. The analytic expression ofsignal-to-noise ratio is calculated by using a new linearized procedure. Itis found that there are three different typies of stochastic resonance inthe model: the conventional form of stochastic resonance, the stochasticresonance in the broad sense, and the bona fide SR. |
