Abstract

We present our recent developments on direct-UV-written planar lightwave circuits (PLCs) based on applications in telecommunications, material characterisation and optical sensing. Interfering two focussed UV spots provides us with an unique capability to simultaneously define channel waveguides and Bragg gratings [1] in a multifunctional silica-on-silicon PLC chip (Figure 1a). This opens new device and application opportunities for laser-based processing. In particular, we have created a range of refractive index sensors and modulators by accessing the evanescent field of our planar Bragg gratings, incorporating functionalised surface chemistry to demonstrate chemical [2] and biological sensing capabilities [3], or liquid crystals to provide electrical wavelength tuning and selectivity [4].
