Continuously-tunable Cherenkov-radiation-based detectors via plasmon index control

Abstract

A recent study [PRB 100, 075427 (2019)], finally, demonstrated plasmon-analog of refractive index enhancement in metal nanostructures, which has already been studied in atomic clouds for several decades. Here, we simply utilize this phenomenon for achieving continuously-tunable enhanced Cherenkov radiation in metal nanostructures. Beyond enabling Cherenkov radiation from slow-moving particles, or increasing its intensity, the phenomenon can be used in continuous-tuning the velocity cutoff of particles contributing to the Cherenkov radiation. More influentially, this allows a continuously-tunable analysis of the contributing particles as if the data is collected from many different detectors, which enables data correction. The phenomenon can also be integrated into lattice metal nanostructures, for continuous medium tuning, where a high density of photonic states is present and the threshold for the Cherenkov radiation can even be lifted. Additionally, vanishing absorption can heal radiation angle distortion effects caused by the metallic absorption.
