Intensity Correlation Function of a Single-Mode Laser Driven by Colored Cross-Correlation Noises in Modulation of a Bias Signal

By using the linear approximation method, the intensitycorrelation function is calculated for a single-mode laser modulatedby a bias signal and driven by colored pump and quantum noiseswith colored cross-correlation. We found that, when the correlationtime between the two noises is very short, the behavior of theintensity correlation function versus the time, in addition todecreasing monotonously, also exhibits several cases, such asone maximum, one minimum, and two extrema. When the correlationtime between the two noises is very long, the behavior of theintensity correlation function exhibits oscillation and the envelopeis similar to the case of short cross-correlation time.
