Abstract
Systems and methods are described that relate to a nanophotonic optical system. The nanophotonic optical system may be configured to transmit light in a range of wavelengths. The nanophotonic optical system includes at least one nanophotonic element, which includes a two-dimensional arrangement of sub-wavelength regions of a first material interspersed within a second material, the first and second materials having different indices of refraction. The at least one nanophotonic element includes a surface having a curvature and an optical phase transfer function dependent on the curvature of the surface. The nanophotonic optical system includes an actuator configured to modify the curvature of the surface and a controller. The controller is configured to determine a threshold optical phase transfer function and cause the actuator to modify the curvature of the surface to provide the threshold optical phase transfer function.
