亚毫安工作在1.55微米波长的高折射率耦合掩埋异质结构分布反馈（BH-DFB）激光器中实现，该激光器由深蚀刻的双量子阱线状有源区组成。当腔长为200 μm、腔面为解理、腔带宽度为2.3 μm时，阈值电流Ith低至0.7 mA，外微分量子效率为23%/腔面。
Sub-milliampere operation was realised in 1.55 µm wavelength high index-coupled buried heterostructure distributed feedback (BH-DFB) lasers consisting of deeply etched double-quantum-well wirelike active regions. A threshold current Ith as low as 0.7 mA and an external differential quantum efficiency of 23%/facet were obtained for a cavity length of 200 µm with cleaved facets and a stripe width of 2.3 µm.
