A new active optical waveguide ion sensor is proposed. Co-polymer matrix membrane based on anionic cation-selective chromoionophore is coated on the patterned glass substrate as waveguide itself. Utilizing thin film membrane, fast response time and high sensitivity are obtained. And sensor could be measured a wide range of Ca++ concentrations ranging from 10-6 to 1M by measuring the absorbance change at 514nm of light. Long-time stability, reproducibility and dynamic range of the proposed sensor are discussed.
