Event Details

Metasurfaces are an emergent class of subwavelength diffractive optics. The individual elements comprising a metasurface may be designed with polarization sensitivity [1, 2] – in this way, metasurfaces can enable optical elements whose far-fields exhibit custom polarization-dependence. Using relatively simple design heuristics based on the Jones calculus, a variety of polarization-dependent optical elements can be realized. These include gratings (of particular interest for polarimetry [3, 4]), lenses, and holograms (the most general case [5]). In this talk, we discuss these metasurface polarization optics, their historical antecedents, their design, and new polarization-sensitive optical elements based on metasurfaces. Metasurfaces ideally provide new additions to the traditional toolkit of polarization optics and may soon reach a level of maturity that sees their inclusion in practical optical systems for polarimetric remote sensing and other applications.
