| 英文摘要 | we propose a method to recover weak pulse signals buried in noise via stochastic resonance (sr) based on optical bistability induced by the free-carrier dispersion effect in the siliconon- insulator (soi) waveguide resonator. the bistable system threshold is determined by the resonator parameters including the waveguide length, mirror reflectivity, and the free-carrier lifetime. a signal with different power levels can be detected by changing the free-carrier lifetime using a reverse-biased p-i-n junction embedded in the soi waveguide. the influence of the system parameters on the sr is quantitatively analyzed by calculating the cross-correlation coefficient between the input and output signals. a cross-correlation gain of 5.6 is obtained by optimizing the system parameters of the soi waveguide resonator. the results show the potential of using this structure to reconstruct and extract weak signals in all-optical integrated systems. |
