本文报道了倒置表面起伏垂直腔面发射激光器（VCSEL），其边模抑制比大于30 dB，最大光输出功率为6.3mW，微分量子效率超过90%。在一个包含渐变层的样品上对160个浮雕装置进行评估，产生了157个单模输出功率至少为2.9mW的激光器，证明了该技术的高效率，尽管制造相对简单。
We present inverted surface relief vertical-cavity surface-emitting lasers (VCSELs) showing a side-mode suppression ratio above 30dB up to maximum optical output powers of 6.3mW and differential quantum efficiencies exceeding 90%. An evaluation of 160 relief devices on a sample incorporating graded layers yields 157 lasers with single-mode output powers of at least 2.9mW, proving the high effectiveness of the technique despite the comparatively simple manufacture.
