Abstract :
Integrated optical sensors, based on evanescent wave sensing, are useful for numerous applications, including medical, environmental and food analysis. System miniaturization is a key issue in their further development. We present the design and fabrication of a novel refractometric transducer, where all optoelectronic components (laser, waveguide, modulators, detectors and sensor pads) are and report on its performance as a refractometer in a flow-through system
