Abstract

The differential gain and nonlinear damping in 16 well MQW lasers has been studied using relative intensity noise (RIN) measurements. Zinc doping the active region increases the differential gain by 50% to 10⁻¹⁹ m² and reduces the nonlinear damping factor by 20% to 0.20 nS. This represents a maximum intrinsic 3 dB bandwidth of 45 GHz.
