title: Reducing the out-of-plane radiation loss of photonic crystal waveguides on high-index substrates.
abstract: Two-dimensional photonic crystal linear defect waveguides on semiconductor substrates are studied. It is predicted that the out-of-plane radiation loss can be reduced by shifting one side of the photonic crystal cladding by one-half period with respect to the other along the propagation direction.
