Multifunctional Metaoptics based on Bilayer Metasurfaces
Multiwavelength holograms, multiwavelength waveplates, and polarization-insensitive 3D holograms based on phase and amplitude masks are demonstrated.
Significance and Impact
The proposed architecture - bilayer dielectric metasurfaces - opens a new avenue for designing complex flat optics with a wide variety of functionalities.
– Independent control of the phase, amplitude, and polarization of light due to a bilayer design
– Two or more optical properties are independently manipulated
– Multiwavelength performance
