论文摘要
作为片上的光源和光学条形码颗粒，纳米仪具有巨大的潜力。我们展示了在红色频谱范围内直径至360 nm（高度198 nm）的超肌Ingap和Ingaasp磁盘激光器。从圆柱和孤立的颗粒中都可以实现光学泵送的室温，单模激光。将隔离的磁盘放在金上时，用parcell增强刺激的发射获得了等离子体偏振子激光。紫外线光刻和质量使纳米虫在晶圆尺度上制造，并具有预期的随机尺寸变化。二氧化硅涂层的纳米粒颗粒从生物细胞内部产生稳定的亚纳米光谱，从635到715 nm的80 nm带宽。
Nanolasers have great potential as both on-chip light sources and optical barcoding particles. We demonstrate ultrasmall InGaP and InGaAsP disk lasers with diameters down to 360 nm (198 nm in height) in the red spectral range. Optically pumped, room-temperature, single-mode lasing was achieved from both disk-on-pillar and isolated particles. When isolated disks were placed on gold, plasmon polariton lasing was obtained with Purcell-enhanced stimulated emission. UV lithography and plasma ashing enabled the fabrication of nanodisks on a wafer-scale, with intended random size variation. Silica-coated nanodisk particles generated stable sub-nanometer spectra from within biological cells across an 80 nm bandwidth from 635 to 715 nm.
