Nanophotonic-enabled optical systems: design and implementation

In this talk, we will discuss our efforts in designing and implementing metasurfaces for optical systems intended for advanced imaging, metrology, and additive manufacturing platforms. These concepts utilize the unique capabilities and scalable fabrication capabilities of nanophotonic devices to enable new systems level functionality. First, we will discuss the utilization of freeform spaceplates as aberration correcting elements for imaging systems. We will show how space can be compressed as a function of incidence angle in a customized manner and how aberration correction capabilities can be enhanced with conformal curvilinear spaceplates. Second, we will discuss the utilization of metasurfaces for additive manufacturing, where we parallelize two photon polymerization processes in a scalable manner using large metasurface arrays. Third, we will discuss the implementation of a nanophotonic-enabled snapshot hyperspectral Mueller polarimetry imaging system, in which the combination of nanoscale polarization optics together with machine learning-enabled data processing enables high speed hyperspectral polarimetry functionality.
