ABSTRACT:

In this talk, I will discuss a new class of optical materials, termed metamaterials, that are the basis for ultra-compact optical devices, ranging from gratings to lenses. These artificially structured materials consist of ensembles of metal and dielectric nanostructures, and have wavefront responses that can be precisely tuned based on the precise geometric configuration of these nanostructures. I will discuss the general principles behind the design of metamaterials and introduce a new class of ultra-high efficiency metamaterials that are designed using topology optimization. These devices utilize qualitatively new types of light-matter interactions based on strong near-field interactions between the nanostructures, and they enable new diffractive optics phenomena compared to the current state-of-the-art. To demonstrate the power and versatility of our design approach, I will present devices that can efficiently deflect light to extreme angles, exhibit anomalous refraction, and multiplex different beam steering functions for differing wavelengths. I will also discuss and demonstrate how these concepts can generalize to ultra-high efficiency, large numerical aperture metalenses. We envision that high performance computational design and big data approaches will be essential to defining and designing the next generation of nano-based optical devices.
