Abstract
Small optics (femtooptics) may be made with optical metasurfaces or diffractive surfaces. Baffles may be formed in the femtooptics with through-glass-via techniques or a variety of etching strategies. Femtooptics may in addition be made using wafer stacking techniques. Variations and combinations of these approaches lead to femtooptics manufacturable in vast quantities by semiconductor wafer processing techniques, also referred to as wafer level optics.
