CLASS:PUBLIC
DESCRIPTION:Metasurfaces have produced exciting new advancements in optics.
  These two-dimensional planar structures allow for precise control of the 
 electromagnetic wavefront via induced sharp phase variations in transmitte
 d and reflected waves\, and aim to replace bulk-optical components for ult
 ra-thin\, flat\, highly miniaturized\, and high-performance optical device
 s. I will highlight a selection of experimental successes and challenges i
 n the design and fabrication of meso-scale cavities with metasurfaces and 
 photonic crystals for experiments with atomic ensembles. In particular\, f
 iber-integrated permeable photonic crystal mirrors\, slow-wave structures 
 with dimerized high-contrast gratings (DHCG)\, and focusing polarization d
 ichroic meta-mirrors made by the Nanophotonics and Quantum Optics (NPQO) g
 roup from the University of Waterloo.\n&nbsp\;
