(color online) (a) The laser frequency responses of CSLC1 for different bias currents. (b) Fitted results when the laser frequency response of 13 mA is subtracted from the laser frequency response for other higher bias currents. (c) Damping factor versus the relaxation oscillation frequency squared (the slope gives a value of 0.3 ns for K-factor).
