Direct UV written waveguides and Bragg gratings in novel substrates

Abstract
Direct UV writing provides a method to rapidly prototype planar waveguides with Bragg gratings. Typically performed in silica-on-silicon, here we introduce alternative geometries for planar lightwave circuits including an innovative flat fibre fabricated via MCVD.
In Bragg grating devices etched windows provide access to the optical field to realise refractive index sensors and modulators. However, this geometry is limiting in the way in which the liquid can interact with the optical mode. Some of our current work we investigate the use of a machined groove to provide a vertical, high optical quality trench. Optical waveguides are then UV written to allow evanescent lateral access of the mode to a fluid placed in the trench. This seemingly subtle change in geometry provides greatly increased flexibility to tailor the interaction between the optical mode and the surrounding material. We shall present our continuing research in these areas.
