In the bookkeeping analysis for QW lasers, the 3D linear gain Go(3D) was obtained by an expression similar to Eq. 115) w i t h Prj replaced by Prj/dz so that Go(3D) = Go/dz where G O - Go(2D) is the 2D gain coefficient and dz is the QW width. 115) relates the 2D gain coefficient Go to the 2D density of states Pry [see Eq. 110)]. The optical confinement factor was F(3D) = dz/t, where t is the effective optical mode width. The 3D carrier density N3D was related to the 2D carrier density (N - N2D) by N3D = N/dz.

These phenomena are called hot carrier effects. The temperature increase and the spectral distortion will lead to differential gain degradation and a large damping effect on the modulation response through a large nonlinear gain coefficient. Thus the high-speed modulation performance is degraded. Each of these different theories captured certain important aspect related to the modulation dynamics of QW lasers. , the injected carriers outside the QW can significantly influence the modulation response.
