Description
Metalenses are optical devices that implement nanostructures as phase shifters to focus incident light. Their compactness, simple fabrication and low cost make them a novel viable solution for increasing light collection efficiency in particle detectors with limited area coverage by light sensors. We report on the performance of metalenses in increasing the light collection efficiency of silicon photomultipliers of various sizes and find a five-fold increase in signal for a 1.3x1.3 mm$^{2}$ SiPM when coupled with a metalens of a 10 mm diameter. Our results are found to be in agreement with the light transmission characterization of the metalenses and geometrical considerations such as the focused beam profile.
