2023 Franklin Medal winner Engheta is one of the world’s biggest names in wave physics. The Penn Engineering professor is renowned for his unique approach to science, combining technical brilliance, creativity, and care.
Columbia Engineering researchers have developed a new class of integrated photonic devices “leaky-wave metasurfaces” that convert light initially confined in an optical waveguide to an arbitrary optical pattern in free space. These are the first to demonstrate simultaneous control of all four optical degrees of freedom, setting a world record. Because they’re so thin, transparent, and compatible with photonic integrated circuits, they can be used to improve optical displays, LIDAR, optical communications, and quantum optics.
