Abstract

We present our recent developments in direct-UV-written integrated optical devices, based on applications in telecommunications, material characterisation, and optical sensing. The inherent advantages of this channel definition technique over traditional etching based approaches are reiterated and demonstrated in the production of small angle, low loss X-couplers with negligible polarisation dependence. Interfering two focussed UV spots also provides us with the capability to simultaneously define a channel waveguide and Bragg grating, opening new device and application opportunities. Such structures provide a method to quantify the photosensitivity effects observed in conventional multilayer substrates, and assess the core uniformity of a novel 'flat-fibre' format recently developed within the ORC. We will also discuss electrically tuned Bragg gratings via liquid crystal overlayers, displaying a dynamic range in excess of 100GHz for use in dynamic optical networks.
