Abstract :
We predict and observe the formation of a compact surface bound state in the continuum due to an optical Fano resonance. We employ a one-dimensional array of optical waveguides with an additional side-coupled waveguide inducing the resonance, and prove that the localized mode amplitude vanishes completely at all locations beyond the resonant waveguide.
