Arbitrary and Reconfigurable Optics

Speaker: David Miller, Electrical Engineering, Stanford University
Location: Spalding Laboratory 106 (Hartley Memorial Seminar Room)

Abstract: Historically, optics was based on materials formed into regular shapes, such as a lens, mirror, or grating, but neither these approaches nor recent extensions like metamaterials are "universal" – we did not know, for example, how to perform many "legal" optical operations, such as separating arbitrary overlapping "orthogonal" light beams without loss. Recently work, however, shows how to break down any legal linear optical component into a mesh of two-beam interferometers [1,2]. Surprisingly, there is even a way to have such a mesh design itself, without any calculations, opening up a new field of self-configuring, self-correcting, and self-stabilizing optics [1,2], and these meshes are well-suited to silicon photonics implementations. Potential applications include mode multiplexing/demultiplexing in telecommunications, self-aligning beam couplers, automatic tracking of targets, automatically finding the best channels through a scattering optical system, networks for quantum applications, and many others. This different way of looking at optics has also led to a surprising fundamental advance in rewriting and extending Kirchhoff's law of thermal radiation [3]. The talk will introduce these ideas and related new directions in optics.
