论文摘要
金属镜是光学设备，可将纳米结构作为相位变速器实现，以聚焦入射光。它们的紧凑性和简单的制造使它们成为潜在的具有成本效益的解决方案，可提高光敏面积覆盖率有限的粒子探测器的光收集效率。 Here we report on the characterization and performance of metalenses in increasing the light collection efficiency of silicon photomultipliers (SiPM) of various sizes using an LED of 630~nm, and find a six to seven-fold increase in signal for a $1.3\times1.3~\mathrm{mm}^2$ SiPM when coupled with a 10-mm-diameter metalens manufactured using deep ultraviolet stepper lithography.这样的改进对于子孙后代的粒子探测器可能很有价值，尤其是在罕见的搜索中使用的粒子探测器，例如暗物质和中微子双β衰变。
Metalenses are optical devices that implement nanostructures as phase shifters to focus incident light. Their compactness and simple fabrication make them a potential cost-effective solution for increasing light collection efficiency in particle detectors with limited photosensitive area coverage. Here we report on the characterization and performance of metalenses in increasing the light collection efficiency of silicon photomultipliers (SiPM) of various sizes using an LED of 630~nm, and find a six to seven-fold increase in signal for a $1.3\times1.3~\mathrm{mm}^2$ SiPM when coupled with a 10-mm-diameter metalens manufactured using deep ultraviolet stepper lithography. Such improvements could be valuable for future generations of particle detectors, particularly those employed in rare-event searches such as dark matter and neutrinoless double beta decay.
