A comparison is made between 16 well zero-net-strain and conventionally strained MQW lasers. Short devices of each structure exhibit low threshold currents and high output powers. For both types of device, the value of T0 is found to be smaller than for 16 well unstrained lasers. Analysis of RIN spectra imply maximum 3 dB bandwidths in the range 34–42 GHz.
