Beaming Effect and Directional Emission from Photonic-Crystal Waveguides

Morrison, Steven; Kivshar, Yuri


It is known that free-space focusing of light from sub-wavelength apertures, the so-called beaming effect of light, can be achieved through the excitation of radiative surface modes and their subsequent constructive interference in space surrounding the apertures. This effect, studied extensively in metallic thin films, has recently been shown to exist in photonic-crystal structures. In this paper, we present a comprehensive study of the beaming effect and light directional emission achieved...[Show more]
