摘要

我们报道了一种利用空间光调制器(SLM)通过动态光镊对单阱半导体纳米线的发光特性进行空间映射的新方法。由于能够控制捕获焦点相对于激发源的轴向位置，可以沿着纳米线的长轴探测组合物。我们还探索了调整捕获光束形状以提高长纳米线(> 5 μm)轴向捕获刚度的可行性。

PL mapping and optimized optical trapping of nanowires SLM beam shaping

We report a novel method for using a spatial light modulator (SLM) to spatially map the luminescent properties of single trapped semiconductor nanowires by dynamic optical tweezers. Being able to control the axial position of the trapping focus with respect to the excitation source, the composition along the long axis of the nanowire can be probed. We also explore the feasibility of tailoring trapping beam shape to enhance the axial trap stiffness for long nanowires (> 5 μm).
