Design and fabrication of high-efficiency fibre couplers for nanophotonic devices

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 μm is described. The...

Zusammenfassung:	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 μm is described. The fabrication of the ridge waveguide using chemically-assisted ion-beam etching has been optimised.
