Spotlight summary: Researchers implement three-dimensional photonic crystal waveguides. To form these waveguides, they introduce defects in a woodpile photonic crystal composed of eight stacked layers of rods. Low-loss guiding at near-infrared frequencies is shown both for vertical (perpendicular to the rods) waveguides as well as for L-shaped ones composed of a vertical and a horizontal waveguide (created by removing a segment of a rod). This work constitutes an important step toward the controlled three-dimensional guiding of light in photonic crystal devices.
