A novel fiber-optic surface plasmon resonance sensor for detection of Cu 2+ ions in an aquatic environment is proposed and experimentally demonstrated. The proposed sensor is fabricated by splicing no-core fiber between multimode fibers and then functionalizing the sensor surface with gold film and...
