a Plot of Fourier transformed weight distribution as a function of wavenumber k for various values of gain (mu=f' u_{0})): (mu=0}12,0}15,0}18,0}2,0}22).
Open image in new window Fig. 3 Light current characteristics of quantum dot lasers for various values of gain compression factors.
Despite gain compression factor limits small-signal response of the quantum dot lasers, the eye diagram of the large-signal modulation of the laser is improved for large values of gain compression factor.
From this result it is clear that the loop response time depends on the value of the damping factor, ζ, and its proper choice depends on the values of gain and natural frequency.
In the plot, for each utilization value, it is possible to see the minimum and maximum values of gain per task, the median and the mean (in the form of a diamond shape), the first and third quartiles, and finally, the outliers in the shape of a cross.
As demonstrated in the supporting information (figures S3 and S4), these changes had no effect upon the qualitative predictions made in the paper, although extreme values of gain shallowness constant A had some effect upon the trends seen.
