Spatially Multiplexed/interleaved Dielectric Metasurface Optical Elements

This invention facilitates the realization of optical elements with spatially multiplexed/interleaved phase profiles to achieve a high packing density of distinct optical elements on a surface. These new optical elements can achieve new and/or improved optical functionalities that are currently unreachable by conventional optical components. The interleaved optical metasurface elements are compact, lightweight and can perform multifunctionality in the same physical space. The researchers believe this is the first demonstration of ultrathin, single height optical elements.
The phase profile design of metalenses was implemented using dielectric gradient metasurface technologies described in Stanford docket S13-484 and US Patent 9,507,064. The design principle can be applied across a wide range of frequencies, and to control other wave phenomena such as acoustics waves.
