Abstract :
The nonlinear damping K-factor value in a strained layer multiquantum well (MQW) DFB laser has drastically decreased to 0.13 ns, about half of that for unstrained MQW lasers. This is mainly due to the increase in differential gain by about a factor of two. The estimated intrinsic maximum bandwidth is 68 GHz.
