Abstract

A large improvement in the high speed characteristic of strained layer multiquantum well (MQW) DFB lasers with a selfaligned constricted mesa structure is described. A very low chirp of 4.2Å at 10 Gbit/s was obtained due to an increased differential gain as large as 4.6×10^−l2m³/s and a reduced α parameter less than 2.
