Intensity Correlation Function

The effects of the correlations between real and imaginary parts of the quadratic pump noise on the normalized intensity correlation function and the associated relaxation time of a single-mode laser model were investigated. The expressions of the intensity correlation function C(s) and the relaxation time Tc were derived. Based on numerical computations, we found that Tc monotonously increases as the strength λp of correlation between the real and imaginary parts of quadratic pump noise increases and the larger λp value is, the slower C(s) decays. The presence of correlations between the real and imaginary parts of the quadratic pump noise causes the intensity fluctuation to increase.

Output Snr

The output power and the signal-to-noise ratio (SNR) of a single-mode laser system are calculated in the case of the laser model with periodically modulated noise. The corresponding stochastic resonance (SR) phenomena are discussed and compared with the case without periodically modulated noise. It is shown that the main difference between the two noise laser models exists in the SNR as a function of signal period. There appears resonance and suppression coexisting phenomenon for the model with periodically modulated noise, which can be utilized to restrain or optimize the output SNR of the system. Whereas, SR is absent for the model without periodically modulated noise, and the SNR just increases monotonously with signal period.
