Demonstration of highly efficient waveguiding in a photonic crystal slab at x=1.5{micro}m wavelengths

Lin, Shawn-Yu L.; Chow, Kai-Cheung

Highly efficient transmission of 1.5 {micro}m light in a two-dimensional (2D) photonic crystal slab waveguide is experimentally demonstrated. The light wave is shown to be guided along a triple-line defect formed within a 2D crystal and vertically by a strong index-guiding mechanism. At certain wavelength ranges, a complete transmission is observed, suggesting a lossless guiding along this photonic 1D conduction channel.
