InGaAsP/lnP strained MQW laser with integrated mode size converter using the shadow masked growth technique

摘要

The authors report the realisation of a planar buried-heterostructure (PBH) strained multiquantum-well (MQW) laser emitting at 1.52 mu m with integrated vertical taper using the shadow masked growth (SMG) technique. The threshold current is 8 mA and the coupling loss to a cleaved single-mode fibre is only 3.3 dB.
