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. A reduction of the structure under both forward and reverse bias is obtained, with no degradation of the optical properties of the source.
