Abstract

A remarkable improvement has been attained for intermodulation distortion and spectrum linewidth performance for 1.3µm DFB LDs by introducing thin barrier MQWs and short cavity configurations. Less than -85dBc in 3rd order intermodulation distortion and more than 50MHz in spectral linewidth have been simultaneously obtained from devices modulated by two 1.5 GHz signals.
