Query: Compact surface Fano states embedded in the continuum of waveguide
  arrays   We describe theoretically and observe experimentally the formation of a
surface state in a semi-infnite waveguide array with side-coupled waveguide,
designed to simultaneously achieve Fano and Fabry-Perot resonances. We
demonstrate that the surface mode is compact, with all energy concentrated in
few waveguides at the edge and no field penetration beyond the side-coupled
waveguide position. Furthermore, we show that by broadening the spectral band
in the rest of the waveguide array it is possible to suppress exponentially
localized modes, whereas the Fano state having the eigenvalue embedded in the
continuum is preserved.
