Schematic of ultra-compact high-resolution spectrometer using flat optics. (IMAGE)
Caption
a, A schematic diagram of the proposed metasurface spectrometer based on wavelength dependent multi-foci metalens model. b, Field distributions on the focal plane under the illumination of monochromatic incident light beams with different wavelengths. c, Field distribution on the focal plane under the illumination of polychromatic incident light beam (left panel). By analyzing the normalized intensities on the ring, five central wavelengths of the polychromatic incident light beam are obtained (right panel).
