摘要

介绍了一种基于双曲极化耦合发射的新型光学显微镜。通过采用双曲超材料作为衬底，我们发现在HPCE显微镜下，与玻璃衬底上的全内反射荧光（TIRF）相比，荧光强度增加了近6倍。此外，我们实现了精确的，随时间的荧光强度的控制调制入射角与电激扫描。这种可调性为超分辨率荧光显微镜和高灵敏度传感提供了广泛的应用潜力，实现了实时荧光强度调节。

Hyperbolic polariton-coupled emission optical microscopy

A new type of optical microscopy based on hyperbolic polariton-coupled emission (HPCE) is demonstrated. By employing hyperbolic metamaterials as the substrate, we show a nearly 6-fold increase in fluorescence intensity in the HPCE microscope compared to total internal reflection fluorescence (TIRF) on glass substrates. Moreover, we achieve precise, time-dependent control of the fluorescence intensity by modulating the incidence angle with a galvo scanner. This tunability offers extensive potential for applications in super-resolution fluorescence microscopy and high-sensitivity sensing, enabling real-time fluorescence intensity adjustment.
