Abstract :
A new buried heterostructure (BH) is proposed for high-speed optical sources, based on selective regrowth of semi-insulating (SI-) InAlAs around an active mesa stripe. The performances of a first BH laser structure realised using SI-InAlAs were compared to that of standard InP:p/InP:n BH lasers, showing a reduction of the structure capacitance with no degradation of the threshold current nor of the external efficiency.
