Nanostructured metasurfaces for optical wavefront manipulation

In this talk, we discuss our recent experimental efforts on nanostructured metasurfaces to manipulate the optical wavefront using advanced lithographic techniques. In the talk, we will discuss their functionalities for augmented reality, wavefront structuring and control, filtering, spectrometry, polarimetry, and others. We will also discuss the opportunities and challenges to scale these nanostructured surfaces to larger dimensions using alternative fabrication techniques.
