Conferences

Event Details

John A. Paulson School of Engineering and Applied Sciences
Harvard University

Subwavelength spaced arrays of nanostructures, known as metasurfaces, provide a new basis for recasting optical components into thin planar elements, easy to optically align and control aberrations, leading to a major reduction in system complexity and footprint as well as the introduction of new optical functions.

The planarity of flat optics will lead to the unification of semiconductor manufacturing and lens making, where the planar technology to manufacture computer chips will be adapted to make CMOS compatible metasurface based optical components for high volume markets like cell phones. Polarization sensitive and depth cameras will be discussed. Metasurfaces also offer fresh opportunities for structuring light as well as dark.

Professor Capasso will discuss devices that enable light’s spin and OAM to evolve from one state to another along the propagation direction and multifunctional metasurfaces. Finally, the demonstration of 2D phase and polarization singularities and the unique applications that they will lead to will be discussed.
