Paper Abstract

The continuous penetration of optical data transport into diverse applications is driving an imperative to find lower cost fabrication routes to high performance waveguides and devices. Strip-loaded waveguides (SLWG) offer a unique opportunity to enable ultra-low cost processing and excellent performance in these applications. In this paper we will show that simple waveguides and devices may be fabricated that have compelling performance metrics. Similarly it is shown that the waveguide design is easily accomplished and that the designs may be rendered with limiting precision using standard process tool-sets. The combination of good design and facile manufacturing practice suggests that, unlike conventional waveguide technology, the SLWG is eminently suited to a wide variety of applications. It will also be shown that the simplicity of the processing offers new opportunities to apply this approach to waveguides in a wide variety of materials and on diverse substrates. Forward design and rendition of devices with excellent reconciliation of measured performance with the design parameters provides a feasibility proof for the validity and manufacturability of the SLWG. Perhaps contrary to pre-conception it is proven that very low coupling loss with normal, single mode, fibres is readily achieved with waveguides of this type. This has been shown both by simulation and via the measured performance of devices. Processing of the test artifacts was via conventional silica-on-silicon planar waveguide manufacturing processes. However, other processes are shown to offer a strong proposition for much lower cost and a diversification of the utility and applicability of waveguides on many substrates.
