Compact folded metasurface spectrometer

Here, the authors introduce the folded metasurface optics architecture by demonstrating a compact high-resolution optical spectrometer made from a 1-mm-thick glass slab. The spectrometer has a resolution of 1.2 nm, resolving more than 80 spectral points in a 100-nm bandwidth centered at 810 nm.
