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.
It turns out that butterflies are just as striking in thermal as they are in the visible light spectrum. According to a study published in Nature by researchers from Columbia Engineering and Harvard University, it's possible to examine the thermodynamic properties of butterfly wings and the importance of radiative cooling in keeping these delicate structures fluttering.
