Resonant waveguide gratings (RWGs) are thin-film structures, where coupled modes interfere with the diffracted incoming wave and produce strong angular spectral filtering.The combination of two finite-length impedance matched RWGs allows creation a passive beam steering element, which is compatible up-scalable fabrication processes.Here, we propose design method to create large patterns such elements able filter, steer, focus light from one point source another.The based on ellipsoidal mirrors choose system confocal prolate spheroids focal points observation point, respectively.It finding proper orientation position each RWG element pattern, that phase constructively preserved at point.The techniques presented here could be implemented in variety systems, large-scale needed, as optical security, multifocal or monochromatic lenses, biosensors, see-through combiners for near-eye displays.
