Abstract

A spectrometer is a type of apparatus that measures the intensity of spectra at different wavelengths utilizing dispersive components and detectors. In recent years, with the increase of application scenarios and demands in scientific research and industrial fields, researchers have make efforts in the miniaturization of spectrometers and there have been many new developments. Among them, the application of metalenses in spectrometers has made great progress. As a kind of two-dimensional subwavelength microstructure, metalens can flexibly control the phase, amplitude and polarization of electromagnetic wave. On account of its small size, light weight and planar characteristics, researches have been conducted to replace conventional optical components with metalens. In this paper, we introduce the design principle of metalenses, and summerize different kinds of miniaturized spectrometers using metalenses, focusing on the dispersion mechanism, optical characteristics and performance of efficiency of these spectrometer system. These applications of metalenses to spectrometers take advantage of their refraction, differaction and polarization characteristics and can be beneficial to exploit other complex functions. We discuss current challenges, potential application fields and promising future developments of metalens design for spectral analysis.
