Abstract

Quantum Well Lasers

Benefitting from the interaction of the GaAs/GaAsP strained quantum well and InAlAs active region dislocation blocking layer, in article number 2300348, Jian Li and co-workers show that the threading dislocation penetration to the quantum well region of the silicon-based quantum well lasers can be bended and blocked. By the introduction of this strain compensate stress control structure, the 850 nm room temperature continuous wave emitting silicon-based quantum well laser exhibits a 94.2 mW power output, a 715 Acm–2 threshold current density, and enhanced reliability.

具有有源区位错阻挡层的硅基 850 nm GaAs/GaAsP 应变量子阱激光器
量子阱激光器 得益于 GaAs/GaAsP 应变量子阱和 InAlAs 有源区位错阻挡层的相互作用,在文章编号 2300348 中,李健和合作者展示了可以弯曲和阻挡穿透到硅基量子阱激光器量子阱区的穿线位错。通过引入这种应变补偿应力控制结构,850 nm 室温连续波发射硅基量子阱激光器显示出 94.2 mW 的功率输出、715 Acm-2 的阈值电流密度和更高的可靠性。
