Abstract
We study adiabatic mode transformations in waveguides that rely on subwavelength holes with progressively-varying dimensions. The variation synthesizes an artificial material with a gradient effective index. Two devices are presented, a microcavity with short tapers incorporated at the four reflector extremities, and a taper between a conventional waveguide and a photonic crystal waveguide.
