Abstract
We describe the fabrication and evaluation of a low-loss, high- optical waveguide consisting of heterostructured photonic crystals. The waveguide is composed of a multilayer stack of and is prepared by use of the autocloning technique. Light is guided in the waveguide by the difference in the effective refractive indices of the constituent photonic crystals. By improving the design of the core region so that is has a flat multilayer structure, we achieve for the in-plane direction and net propagation loss of at . Experiments also suggest that the bending loss of the waveguide can be reduced to less than 0.1 dB if the curvature radius is larger than .
