A dual waveguide heterostructure device that couples light from single mode optical fibres into nanophotonic devices with an overall modelled efficiency of 81% has been investigated. A four-stage taper design for the ridge waveguide which allows for a total device length of 610 mu m is described. The fabrication of the ridge waveguide using chemically-assisted ion-beam etching has been optimised. (c) 2007 Elsevier B.V. All rights reserved.
