摘要

研究了COD阈值大于5•106 W/cm2的高效sld原型。具有4 μm宽有源通道的单空间模式样品的连续波输出功率大于200 mW。初步的100mw级可靠性试验取得了成功。结果表明，在采用SM光纤反射器实现的双通工作模式下，可以显著提高外部效率。结果表明，基于相同QW异质结构的20 ~ 30 μm有源通道宽度的多模SLD可以保证在大于0.5W的输出功率水平下足够可靠地工作。

Towards 1.0 W CW reliable SLD at 840 nm

The prototypes of high-efficiency SLDs with COD threshold of more than 5•106 W/cm2 were investigated. Single spatial mode samples with 4 μm-wide active channel exhibited CW output power of more than 200 mW. Preliminary reliability tests at 100 mW level were successful. It was shown that in double-pass operation mode achieved using SM fiber reflector, external efficiency can be increased significantly. The estimations show that multimode SLD with 20-30 μm active channel width based on the same QW heterostructure may ensure reliable enough operation at output power level of more than 0.5W.
