摘要
我们在硅平台上实现了具有AlInAs-oxide电流约束结构的GaInAsP/SOI混合fabry - p (FP)激光器。采用等离子体激活键合技术,采用湿氧化法氧化GaInAsP量子阱上方的AlInAs层。在未氧化条纹宽度为4.5 μm,腔长为500 μm的条件下,获得了阈值电流为50 mA,外差分量子效率为11%/facet。
GaInAsP/SOI hybrid laser with AlInAs-oxide confinement structure fabricated by plasma activated bonding
We realized GaInAsP/SOI hybrid Fabry-Pérot (FP) laser with AlInAs-oxide current confinement structure for PICs on a silicon platform. Using hybrid wafers by a plasma activated bonding technique, an AlInAs layer just above GaInAsP quantum wells was oxidized by wet oxidation. A threshold current of 50 mA and an external differential quantum efficiency of 11%/facet were obtained with the unoxidezed stripe width of 4.5 μm and the cavity length of 500 μm.
