Abstract

Developing approaches to power efficient and high-throughput computing is critical for meeting ever-growing computational requirements. There is significant interest in using optics to perform computational tasks such as performing image processing tasks in analog, eliminating the need for computational resources. In this work, we demonstrate inverse-designed meta-optics capable of isotropic 2D edge-detection with large numerical apertures. To highlight the versatility afforded by the optimization-based approach, we design a multifunctional device that performs a variety of processing tasks based on polarization, wavelength, and diffraction order. These devices can be used in novel computer vision and computational imaging applications.
