We propose a novel photonic crystal waveguide configuration consisting of coupled-resonator optical waveguides at the termination to obtain enhanced transmission and beaming of light. We show theoretically that such a configuration can collimate the light output from a photonic crystal waveguide over a wide bandwidth range. The mechanism explained in this paper may be easily extrapolated to the photonic crystal configuration of air holes in a dielectric substrate.
