摘要：

A 1.3 mu m laser has been developed with a butt-jointed selectively grown spot-size converter (SSC). The SSC, vertically tapered waveguide and strained multiquantum well (MQW) active region are independently optimised. The laser was buried with semiinsulating InP to reduce optical loss in the SSC. A threshold current of 7mA and an output power of > 20mW were obtained. Minimum coupling loss to a flat-end fibre of 1.06dB was achieved. Long-term stability was also confirmed.
