Self-configuring photonic circuits and limits in optics

Keynote talk at Photonics West, 2023 – “Self-configuring algorithms, topologies and fundamental limits for photonic circuits and structures” Micro- and nano-fabrication allow new optical systems well beyond previous conventional optics. These possibilities cause us to think of optics quite differently. One approach uses “circuits” with topologies and configuration algorithms. Some such topologies support algorithms allow… Read more Self-configuring photonic circuits and limits in optics

Why optics needs thickness

This Science paper (D. A. B. Miller, “Why optics needs thickness,” Science 379, 41-45 (2023)) shows why and when optical systems need thickness as well as width or area. Understanding this thickness matters as we try to make ever thinner cameras or exploit the emerging possibilities of nanophotonics and flat optics, such as metasurfaces. We… Read more Why optics needs thickness
