论文摘要
我们提出了染料掺杂的手性颗粒的增益辅助对映选择性方案，表明可以使用外部可控制的参数调整光学拉力和推动力。通过控制染料分子的浓度和泵送速率，我们实现了极端混合物的全光学手性分辨率，并在不依赖干扰的情况下实现了小型偶极性手性颗粒的对映射。该方案适用于无损和有损的等离子手性颗粒，使其成为手性传感，药物发现和分子分离的有前途的方法。
We propose a gain-assisted enantioselective scheme in dye-doped chiral particles, demonstrating optical pulling and pushing forces that can be tuned using externally controllable parameters. By controlling the concentration of dye molecules and pumping rate, we achieve all-optical chiral resolution of racemic mixtures and enantioselection of small dipolar chiral particles without relying on interference. This scheme is applicable to both lossless and lossy plasmonic chiral particles, making it a promising approach for chiral sensing, drug discovery, and molecular separation.
